Music Recommendation tool/service

[BRMMA]

I spent most of my teens and early/mid-20's DJing and as i had little to do with my time loved spending pretty much all weekend either in record shops or clubs playing.

I've recently started playing again, though just for fun as i have no intention of DJing out again, at least not on a regular basis. however i no longer have the time to trawl record shops or online sites for music especially as it seems so much music now spans multiple genres (especially in dance music) so it's difficult to know where to look

anyway, to the point. does anyone know of a decent site that recommends tracks for you based on you entering a genre or the names of tracks you like? i know certain online stores do this based on your purchases but they're typically a little more mainstream and only sell stuff once it's released on major labels

many thanks
