Christ material design is garbage, the new UI is awful, it displays almost no information compared to the good one, adds another step or menu to almost every single user interaction that wasn't removed BuT It LoOkS nIcE.
Interface elements aren't supposed to overlap.
Blocked out text like that looks AWFUL, it always has and always will
It was nice having quick access to the EQ/visualisation stuff by swiping from the edges instead of buttons that don't fade/can be set to transparent, or at least having most of the buttons that clutter the interface now back behind a dropdown.
It was nice when back took me to the previous screen instead of the home screen.
I did like swipe up and down for swapping albums, but dragging down for the now playing is actually ok too, but having the album art bubble next to every track is tacky.
It shows 9 tracks on the good interface and 4 on the new one, with no obvious sign which track in the now playing list is the on currently playing, just an extra element on the bottom of the screen.
I'll conceed I only play albums instead of playlists so it might work better with a couple of hundred tracks but it'd be nice to have either or, in either case a more compacted menu would work better imo.
I understand that you've gotta update the look and feel so it doesn't get stale, and so you can clean things up but Poweramp started as a clean, tight interface and the design language has been more or less consistent, now it's getting changed up because ????????
It is butter smooth though, even on an older phone I have it runs really well, other than that sort by album artist bug a few other people have mentioned the back end seems pretty solid.
As for people complaining about "what do you look at the interface all the time?", Yes, yes I actually do I have an android tablet built in to the dash of my car running Poweramp... I have yet to test it there but ironically the new interface would probably actually work well for me there.
