In regards to the whole genre issue though I wouldn't say it's that important - I've often found that some tunes that I might use as warm up tunes are the equivalent of peak-time tunes for other DJs, and vice versa.
It's great when a tune can work in different contexts I think. Personally I find the techy sounds of SvD and such more more agreeable at lower bpms to higher, when it has a much more progressive feel to it. At higher bpms I just find it noisy
Ultimately though I say there are only two genres of music for everyone. Music you like, and music you don't :smile1:
