These days I'm really into techno and techno/rock and stuff like that -- try searching for these songs:
Thomas Falke "Revolution On The Dance Floor"
Groove Cutter "My Shooter"
Control One "Just A Little Bit"
Ian Carey "Redlight"
Kevin Weg "Dead Radio"
I don't usually go for techno but these are...
yeah, for dance music, basically you've got to get the hottest stuff from the euro-zone,
everything else pretty much sucks..
for example THIS stuff pretty much rocks..... (direct itunes link)
