Hi, developer of Tangerine! here.

I just wanted to note to the few commenters here that version 1.1 introduces presets and rules in the new playlist sheet. It lets you create playlists from specific genres, playlists, artists, etc. The rule editor is improved so that you can pick a bunch of items. You won't have to have one rule for each genre you want to exclude, for example.

Please try it out and send us feedback if you think it needs improvements. Thank you!
