Cover art for Gone Going lyrics by Black Eyed Peas, The

The story of a successful musician forgetting his roots is so old it's cliche. I'd be surprised if this song is directed toward any one artist, because there's no specificity anywhere. Hell, the artist's name is "Johnny" how generic can you get?

And, InsertEmo, Jack Johnson is laid back, but I don't think he's laid back enough to contribute to a song about how much he sucks.
