Be kinda sweet if George W. Bush would choose "Liberty Lies" for his ad campaign... But seriously, I have no problem with an artist doing whatever they like to promote themselves or their music, including doing ads, so long as the corporations they choose to advocate aren't aggregiously corrupt. Hmmm... Might be a problem there, as well as an oxymoron. What I don't like is when somebody buys up the rights to another's art and shamelessly pawns it off, as was the case, I feel, with the king of pop (ha!) and The Beatles' music.
