With Music Launcher you can organize your music into folders. Selecting what to play is as easy as selecting several folders. Music Launcher supports sub-folders, and also individual files can be selected/unselected inside each folder. This way of organizing music has two main advantages over the "modern" way of organizing music as Artists-Albums-Genres-Playlists:
You can have your compilations into folders, and you just need to select those folders to play the desired compilations. In the Artists-Albums-Genres-Playlists way of organizing music this can be achieved only by creating a playlist, which is time-consuming and rigid.

You can listen to different music each time you start listening: just select some folders from your music, including your compilation folders. No need to create a playlist each time you want to listen to something else.
