Does the word "Rock" have to appear in the title? If not, then a no-doubter is "We Built This City" by Starship. It's a sell-out song about not selling out.
This is the song that sprang straight to mind when I saw the thread title.
Falco's Rock Me Amadues
is up there high in the ranks of crapdom as well.
Thank God for that song though, or else there would be no "Planet of the Apes:The Musical" segment on the Simpsons.
