Music Cloud Services?, Just what the RIAA was looking for!

Google Music, icloud, and recently announced bestbuymusiccloudcopycatwhatever, all have users scared that the RIAA could be using these service's like honeypots. Get users to upload their music then sift through them and see which were bought legally online ripped from purchased CD etc, and which were acquired by other means....  basically their letting the users list off if they have any "illegal" music
