What is the best GUI for PI music box using raspberry pi?

Continuing the discussion from How to start a podcast by command line - or how to add latest podcast of a xml RSS feed to playlist? as the question was off-topic where it was posted.:

Rompr, IMHO.

but I guess it depends on your needs.

+1 for Rompr. It has alot of features and makes listening music from Mpd/Mopidy a pleasure.
