Unable to play music from my library

[Jenny!]

I'm not sure if this is a bug with Funkwhale or Otter because I can play music through the Funkwhale web interface just fine.

How to reproduce

1. Sign into funkwhale through otter. My account has its own library.
2. I see songs that are not in my library, but part of the funkwhale instance owners library on the default page that otter opens.
3. I click Radios
4. I click "Your content" to play songs from my library.
5. No music is played and an error pops up. The Radios page is now broken. The following buttons fail to work until I leave the page and come back. "Your content", "Random", "Favorites", and "Less listened.
6. The instance owner can play their own library via otter and the web browser just fine.

Expected behavior

I expect to play music from my library. I can play my library through the web browser just fine.
