I don't know that much about super popular acts, but won't they all? I mean Marina went number one in the UK with Electra Heart...If she can do it I imagine it is easy for all these acts... I just kind of assumed all of katy, Ke$ha, Gaga etc's albums went number one at some point...
You'd think, wouldn't you?
and yet Rihanna who has had 11 US No 1 singles has never had a US No 1 album.
you must be delusional if you think that he won't debut at #1
