So I bought a new pair of Astro A40s and I wanted to legally download free dubstep in aiff. I cant' find any anywhere I acutally can't find much music to listen to in aiff at all even if I wanted to pay for it, but I'd love to just try the headset out by listening to aiff files (I hear the quality is great). Anyone have any ideas? Preferably free legal downloads. I love dubstep.
