Problem type: Something else - I'll add details below

Steps to Reproduce

1. Navigate to: https://www.pandora.com/station/play/2435999837822417781
2. Login
3. Play Music

Expected Behavior:
Music Plays Correctly

Actual Behavior:
Duplicate songs start up part way through the song. Different songs start when moving to new songs. Pausing songs pauses the primary track. Primary track randomly resumes even while the tab is not active. Sound icon on the tab vanishes when main track is paused, even though disconnected track is still running. Appears to happen at the beginning of new songs and at interruptions/buffering.
