Hello! I'm currently using Musicolet as music player app on my android phone, and I really really really like its features. the ones I use the most are the possibility to reorganize the queue just by dragging songs, and the "boolean" operations on playlists (for example, If I have the "favourite" playlist with a lot of songs, and then the "Linkin Park" playlist, and I want to get all Linkin Park songs that are also favourite, I can intersect the two playlists)

any idea?
