One is making headlines for simulating oral sex on stage.
Another is aiming for a comeback after a public, ugly break-up.
A third is really, really weird.
And the fourth major artist releasing a new album this week has actually broken pre-sale records, despite having been utterly unheard of just a few months ago.
Indeed, with numerous singers and record labels hoping to take advantage of the holiday season, this is shaping up to be the most competition week in CD sales history.
Adam Lambert ("For Your Entertainment"), Rihanna ("Rated R"), Lady GaGa ("The Fame Monster") and Susan Boyle ("I Dreamed A Dream") will all compete for the top spot on the charts.
And we're not even counting Britney Spears, who is releasing a collection of her number-one hits (K-Fed is definitely not inclued on that list. Zing!).
Whose new album will you purchase first?
