the grey album - danger mouse
it's basically a mash up of jay-z's black album and the beatles white album.
it's banned but I would recomend this to any music lover, and it can be found on some Grey tuesday sites.
dissing soulja boy ain't exactly hard though:P
For some ulitimate dissage you should listen to T.I rip lil 'flip to shreads
'99 problems lil 'flip ain't one'
