Those are snippets from a project off a friend of mine (the one who also did the Britney Spears unplugged mixes).
The full is gonna be posted REALLY soon at popgoeslive.tumblr.com!!
These are really great! I love the Rihanna and Xtina ones particularly. The Gaga one sounds like it'll be interesting, but that Britney has too much autotune on the vocals (which is not a fault of the producer of these), which clashes with the acoustic setup.
