Hi!
I need to identify these 4 tracks. They were included in a set from june'2010 played by Massimo Cassini on his soundcloud page. I don't know if the tracks themselves are from 2010 or older.
Here are the links:
track-a (http://soundcloud.com/w00t/massimo-cassini-june2010-a/s-ZFQy1)
track-b (http://soundcloud.com/w00t/massimo-cassini-june2010-b/s-OnAQh) --> Glitter - Take Over
track-c (http://soundcloud.com/w00t/massimo-cassini-june2010-c/s-GaqGT)
track-d (http://soundcloud.com/w00t/massimo-cassini-june2010-d/s-rLjIi)

Thanks!
