Will be sure to check those all out. Have to say I am impressed so far though. Very seamless, and everything meshes well.

And since we're sharing our favorite mashups albums, here's mine:
Wu-Tang vs The Beatles: Enter the Magical Mystery Chambers The Mixtape (skip intro, start with C.R.E.A.M.)

edit: Was great. Especially liked Come As Your Kids and Strangletage. Thanks for sharing, and the ping. :)
