For me, if I like the tune I'll buy it.

I also agree with this:

I will agree...I think its really cool when a producers background, thoughts, theories, or ideas reflect their music. Theres a few producers out there where I really respect their opinions and I can see even better what they're trying to explain with their music...not just in techno, but in all different styles of music.
but if a tune makes me want to dance or I think it'll make other people want to dance then I'll buy it regardless of who it's by. Including Pete Tong, lmfao - the man's a legend, knows more about music than I could ever dream to.
