Don't sync down Apple Music tracks please!

I think I've found the cause of many of my "it doesn't play on iOS, but does on my Mac" problems. I'd played with Apple Music a week ago. In doing that, a few of my local tracks end up with Apple Music DRM versions (I still have my old non-DRMed tracks too). When Spotify syncs a "local" track, it can pick either the DRMed version, or the non-DRMed version. You'll only find out it pulled the wrong one when playback grinds to a halt on iOS. 

After removing the Apple Music tracks from the iTunes database, (they're listed under Apple Music), I was able to resync my playlist and the songs which previously wedged up started to play.

Is there a place to file a bug with Spotify? Seems like it really shouldn't be sourcing "local" files that are Apple Music DRMed.
