i would sudest limewire (
www.limewire.com) because its pretty fast. i haven't tryed finding album b4 but i think i've seen a couple when searching for songs. the best part about limewire is that you can get the free version and download the pro one (which you're ment to pay for) through the free one, and its quite abit faster. anyway hope i helped.
P.S:remember its filesharing not stealing
