+queue datamodel
+---------------
+
+Don't need JSON - newline text? split? No need for field names? `test/csv` records? (no heading?)
+```
+QUEUE_KEY: [
+    {
+        "track_id": "BASE64HASH",
+        "performer_name": 'str',
+        "session_owner": '',
+        "weight": float,
+    }
+    "timestamp_play": int,
+]
