"If Apple Corps really wants to do something cutting edge"
What ever gave you that impression. They really want to do something profitable, that's their bottom line. And they don't have the foresight to see how giving away the tracks can generate business.
Are Beatles mixed with Beatles really a mash-up ...or just a puree?
Tom, you have sat radio, no? I've been hearing lots of the "love" album on XM. It's no Dangermouse.
Veronica, I'd suggest taking a weekend trip to Vegas to catch the Cirque do Soleil show that spawned the Love album. You can always get a souvenir CD/DVD after the show - if you still want one.
If Apple Corps really wants to do something cutting edge - release Beatles material as multitrack GarageBand/Acid files and let the REAL mashups begin!
