Best music player with no ads on iOS.

I’ve been using the same app on Mac, and it’s truly amazing. I love the clean interface, but I have three suggestions after using it:
1. Lyrics UI: Currently, it's just a plain white page. It would be much better to have an immersive design like Apple Music (blurred album art background, focused current line, smooth scrolling).
2. Audio Quality Display: It would be great to clearly show the audio format and quality (e.g., ALAC 24-bit/96kHz) right on the main playback screen, as the attached screenshot shows.
3. Playback Bug: After pausing/stopping from the app or Control Center, the Control Center icon sometimes switches back to showing "Play" even though audio has stopped.
Hope these can be addressed in a future update!

Excellent Choice for NAS Music Collection

As someone that keeps their music collection on a Network Attached Storage, so that I can use it with multiple OSs, Cog is totally excellent with this option.
I also appreciate the consistent updates to this application!

Great

Only missing thing is playlist management like creating smart playlists. There is currently no option to resume playing from last position when listening to spoken word books and lectures.

Please ADD last.fm support!

This app is great, but we all need last.fm support. Please add this feature! I’d like even pay for it.
