No DRM = More sales

Here you go.

Who would have thought, DRM free MP3 downloads, that give you the same rights and abilities as a CD (i.e. the ability to make copies, backups, and lend to a friend) have resulted in increased sales for EMI. Some CDs are up by over 300%!

But it's more easily pirateable! This just doesn't make any sense! Bear is driving how can this be?
