What's missing from your current music player?

Hey! I'm the maker of Sonora, a local-first music player with synced karaoke-style lyrics and optional Genius metadata enrichment.

Curious to hear from this community: what's the one thing that annoys you most about Spotify/Apple Music/whatever you use now, or what would make you switch to a local-first player? Trying to figure out what to prioritize for the next beta, thanks for checking out the launch!
