Not enough space on the server to list my favourites. I used to DJ and still love and listen to dance music (even though I am over 21). I once spent a week listening to R&B for 20hrs a day and finally got brainwashed into really liking it .
Edit to add: try some of the french DJs like Claude Challe and Stephan Pompougnac - fantastic stuff!!!
However I have a wide range of tastes (except heavy metal). Artists that have stayed with me over the years include Neil Young, New Order / JD, Tod Rundgren and Leonard Cohen. These days I am listening to a lot of Nick Cave and Richard Hawley. Too much good music out there!
