Update to Cloud Player broke downloading?

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Sign into Cloud player
2. Select songs/albums/ etc.
3. Click Download

What is the expected output? What do you see instead?
A week or so ago I was prompted to save the .amz file. Now it displays a 
message saying that Linux systems can only download songs 1 at a time

What version of the product are you using? On what operating system?
clamz 0.5. OpenSuse 12.1

Please provide any additional information below.
I have followed the link that tells the Amazon website that the downloader is 
installed.

This isn't a problem with the clamz, it's an issue with Amazon, because they 
stopped supporting their own Linux downloader altogether. I've tried changing 
the Useragent, but it hasn't helped - they seem to be using Javascript or some 
other means to profile the system as a Linux host.

So now we're screwed? Downloading songs one at a time from their cloud service 
isn't ideal, especially once that fills up.

Darn, so can you download the amz file from windows? Maybe it's time to set-up 
a virtual machine if so (and can watch Netflix too then).

Sadly, I dumped my windows partition awhile ago.  Guess this makes me
investigate other sources for mp3s...lot of bands have stuff up on
bandcamp, which means they get more of the cut.  But, damn, clamz was
awesome. :(

I bitched to Amazon.  They gave me some BS about how they're protecting me
from my computer and crashes.

The Cloud Player still works if you do the following.

1. Set your User-Agent to something that Amazon thinks is Windows (I tried 
"Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)")

2. Ensure that your 'dmusic_download_manager_enabled' cookie is set correctly 
(click the appropriate link on the clamz homepage)

3. *Log out of the Cloud Player and back in*

4. Select a list of files to download

5. You might still at this point be prompted to install the Amazon MP3 
Downloader; if so, download the installer, and then click the link that says 
"click here to try again after installing the MP3 downloader" or something like 
that.

6. It will prompt you to "authorize your device" (!!) before letting you 
download your files - apparently you can only do this for 10 "devices" at a 
time?  Actually, looking at my account it appears I did this once before, 
though I don't remember doing so.

7. Finally it will give you an amz file that you can download as always.

Note also that the old non-Cloud-Player system is still working, although they 
are making it harder to find: after purchasing a song/album, below the big 
yellow "Play your music in Cloud Player" button, it will say "If you have the 
Amazon MP3 Downloader, you can download your music now."  (Again, this requires 
your cookie be set correctly beforehand - click the link on the clamz homepage 
- and Javascript must be enabled.)

But the moral of the story, of course, is that you should never trust Amazon 
(or any other "cloud" service) to be your only backup.

I just bought http://www.amazon.de/gp/product/B006C1OJLW/ref=dm_ty_trk and I 
could play it in the cloud player or download it, I clicked on download and got 
directly the amz file.

Maybe this is only an issue with the us-store?

My useragent string is "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.1 
(KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1" (it is google chrome)

Confirming that it still works on amazon.de — I just downloaded an album 
without any issue.

Benjamin, thanks for the walk-through, but I can't get past their Linux OS 
detection. Looks like they've torpedoed me as a user. Must be nice to have so 
many customers you can afford to drive them away.

The cookie setting link didn't work for me, but the " Comment by 
[email protected], Aug 9, 2012" at 
http://code.google.com/p/pymazon/wiki/HowToAmzDownload did work:

"
1. When I make One-Click purchases, I get the option at that point to download 
the .amz file, which I can do and open in Pymazon or Clamz and all is well. 

2. If I DON'T download at that point, my only option is the Cloud Player. 3. To 
download in the Cloud Player, I changed my user-agent via User Agent Switcher 
(FF extension) to IE8 and tried a bulk (.amz) download. It still told me I had 
to download the Amazon MP3 Downloader, so I clicked on the download button, 
then simply cancelled the download. After that, I saw a screen that said, "when 
you've installed the MP3 Downloader, click on the 'Download Your Music' 
button", but the button was grayed out. BELOW THE BUTTON, there was a link that 
said, "'Download Your Music' button not working? click here." I clicked and it 
apparently filled in the right cookies for the download to go through and I did 
a full download!

I just bought an album on amazon.de (a One-Click purchase as well) and I was 
given the option to download the songs which promptly started the download of 
the .amz file.

It seems to be kind of hit-and-miss but for me it worked hassle-free. Maybe 
there are regional differences?

I just tried downloading an album from Cloud Player that I had purchased a 
couple days earlier. After following the user agent tricks, I managed to 
download the .amz file. However, clamz then fails to download the mp3 files 
with an error of "ERROR: Error downloading file: The requested URL returned 
error: 500".

It seems that Amazon is now enforcing an "Amazon MP3 Downloader" user agent for 
downloads to work. This pymazon bug has more details: 
http://code.google.com/p/pymazon/issues/detail?id=59. The issue only seems to 
affect amz files from Cloud Player. Changing pymazon to set a User-Agent header 
of "Amazon MP3 Downloader (Pymazon 1.0.17 en_US)" (as in 
http://code.google.com/r/jsphslgr-pymazon/source/detail?r=818aa6ca8405a92379122e
67c5b38d23375e1ea1) fixed the issue for me. clamz should probably do something 
similar.

I could confirm what [email protected] describe is correct.
I have an amz with 5 different mp3

clamz could only download 3 of the 5.
With the other 2 giving me this error 
"ERROR: Error downloading file: The requested URL returned error: 500"

Similar error is returned if using wget to download
   wget {url copy from amz file} -O {mp3 file name}

However, I can download the file successfully if using this user agent 'Amazon 
MP3 Downloader (Pymazon 1.0.17 en_US)'.
   wget --user-agent='Amazon MP3 Downloader (Pymazon 1.0.17 en_US)' {url copy from amz file} -O {mp3 file name}

I get error 500 if I try resuming downloads (with clamz's -r option), but clamz 
would download files from scratch just fine, which is really odd.

Sadly Google Play Music is not exactly much better when it comes to 
downloading. I use it as a write-only cloud storage for my music, but last I 
checked they only let you download songs twice -- even songs you upload 
yourself!

It didn't work for me with the UA changed to IE8, so I changed it to IE6 and 
got a message stating that my browser istn't fully supported. But the Cloud 
Player loaded and gave me an amz that worked for a bulk download.

I wrote a Greasmonkey Script which will work around Amazons Cloud Player 
restrictions:

userscripts.org appears to be down. Perhaps you can put it up at github or 
bitbucket or similar?

My userscirpt is now available here:

I need to find the time to set up updating since userscripts.org seems to be 
down forever. The version Florian posted is not working anymore because amazon 
changed the design of the cloud player. For now you can get a working version 
at the link above.
