Yep, it’s Sic (sic).

File-browser’esque based music player. Good cover-art handling, tap to alternate cover size.

Interesting random-playmode selector, with ‘radio random’, that chooses a random next song, with a random start time in the song.

I like it. UI testing continues.

Nice! I was searching for such a file browser based option. I am a fan of SicMu and I hope this one supports Android Auto, there is nothing else like that out there.

This is a neat find, thanks for posting!
