Being a novice at the whole downloading game myself, this may be totaly wrong :P
But here goes. B-Sides were officialy released on the back of singles and on CDs and the like, so that means that they are offical and can't be downloaded, unless of course you are paying the price for them........
I think this is right.... someone help me out here :)
Anyway i hope this helps :)
I'm not a river or a giant bird, that soars to the sea, an if i'm never tied to anything i'll never be free!
