Any tunes which im having trouble getting hold of i'll go on amazon MP3. Got Turbulence 320 for like 28p a while back.
I've got a massive problem with amazon downloads, they always say its a 320, put it in serato & it comes up between a 200-300. maybe cheap but they're not full 320s. have the same problem with play.com.
I use all of them, shop about, see which is cheaper. Beatport is annoying if you use paypal, buy tracks and the total is under £10, they add 60p to cover their charges, wanted one wav which was cheaper on beatport than dnbarena, until the 60p was added. hassle.
My fav is dnbarena though.
