Why wasn't this fiery rant included on Eminem's last album? Unlike recent smashes "Not Afraid" and "Love the Way You Lie," this newly surfaced track (which didn't make the cut for Recovery) comes without any high concept — just Eminem spewing fantastic bile for five minutes. "I took a hiatus, haters, now I'm back to cause trouble/Got the fuckin' shape of mushroom clouds for thought bubbles," he fumes over producer Just Blaze's martial drum rolls and spare piano line. This is nu-Em at his finest, stone-cold sober but drunk on the sound of his own words. He's got his sense of humor back, too, livening up his vicious verses with a few decent scatological gags and a Brett Favre punch line. Even a flat-toned chorus sung by Blaze can't disrupt Eminem's focus. Just imagine how huge this could have been with a real hooksmith like Drake or Kid Cudi on the assist.

“Is It True”

As the British Invasion reached its peak in 1964, Brenda Lee went from Nashville to London to record one of her hardest-rocking hits, her perky vocal backed by a stuttering, squalling guitar. That guitar was played by session musician Jimmy Page, yet to skyrocket to fame with first the Yardbirds and then Led Zeppelin. "She said to me, 'I've come here to make a record with the British sound,'" remembered producer Mickie Most. "She felt she wouldn't get the same sound in Nashville because they're only just catching up on the British beat group sound of about six months ago."
