Well, Radio 1 in the UK got duped by an act called "Shocka featuring Honeyshot" that is actually an ad for … well, hair styling products. NME reports that the song "Style, Attract, Play" (seems suspicious) was actually performed by an act constructed by an advertising company, and when Shockwaves (the hair product company) was contacted they said "there might be a connection" (after first denying it).
How long until we see this stateside (well, beyond all those damn American Idol songs) where ad companies will be clandestinely building bands to hock products.
I have three words for this: Yvan eht nioj!
