I think it all hangs on where the adverts are, if they put them at the start of tracks then it will never work. I think it would be useful to try new music, but I would never download tracks that had adverts in them, even if they were free.

I run my own system, if I come across some music I may like I download it, if I like it I buy it, simple. I guess this sevice could be useful for that, but I still think they should be thinking more about how they sell their acts to us.

Cheers
