Eminem has emerged from the shadows of a rumor-filled retirement to announce that he'll release a new album, possibly even before the year is up, according to a Billboard.com story citing an interview on SIRIUS rap station Shade 45 (audio via Nah Right).In the interview, which took place at a launch party for Em's new coffee table/bathroom book The Way I Am, the Detroit MC revealed that the Encore follow-up's title is Relapse. He also debuted a new track called "I'm Having a Relapse". As you can hear over in Forkcast, the song's a little half-baked, but at least dude sounds reinvigorated.One question remains, however. What's to Relapse from if the record hits shelves before Detox?
