Diamond Eyes - Bonus Cover Songs (Do You Believe?, Ghosts, Caress)

[truthaddict]

I looked through Wikipedia and Discogs, but can't find any record of these bonus cover songs ever being released on a physical CD.  I would buy them on CD if I can find it.

Have they only been released in digital format so far?  Is there a legit source to buy them in FLAC format?

Do You Believe? (Cardigans Cover)
Ghosts (Japan Cover)
Caress (Drive Like Jehu Cover)
