Eminem has revealed his frustration at discovering that songs from his forthcoming album Relapse had leaked online.
One song, I'm Having a Relapse, found its way onto YouTube in October, while another, which it turns out is called Crack A Bottle, went public just a few days ago.
Speaking about that track, Eminem told Billboard: "It wasn't close to finished, and it even has me doing guide vocals for Dre as a suggestion of how he could lay his verses down.
"It's like someone catches you peeping in your window before you got the Spider Man costume all zipped up! Nobody is supposed to see that. We are gonna finish it up though and get it out there how it's supposed to be."
Eminem has previously confirmed that Relapse will be released some time in the first quarter of 2009.
