Actually make the dj requests work

[Djneedswork]

The recently implemented dj request feature is a good idea in principle but it needs at lot of work. It would be good if when you told it you didn't like a genre or artist or would update itself to not play them. Also it would be good if after it acknowledged a request it actually implemented it. So if you ask for a specific song or artist it did just say "ok here's the song you asked for" and proceed to play something completely different.
