Suggestion: Simple GUI to add music

I apparently didn't comment on this earlier, but I do plan to have this:

1. You will be able to add any number of music repos. Repos just hold a list of different audio titles (and their location on the web).
2. The client will be able to create playlists from any song on a connected repo. Do note that the server will enforce a playlist length limit though (this is already implemented on the server, and a config in the server settings page exists to change it).

I unfortunately won't be able to do much this month as I will be quite busy, but start of next month I will have a fair amount of free time and should be able to start working on this again.
