New Eminem, 50 Cent Songs Hit Radio, Web

New 50 Cent song, `I Get It In,` debuted Monday on New York radio station Hot 97.

There's still no solidified release dates for upcoming albums from Eminem and 50 Cent, but new music from both rappers has emerged in the past 24 hours.

Eminem's "Crack a Bottle," which features 50 Cent as well as his mentor Dr. Dre, leaked online Tuesday; an earlier version without the guest appearances had leaked in November, much to the dismay of Eminem.

"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," he told Billboard at the time. His first album in more than four years, "Relapse," is expected this spring via Interscope Records.

Meanwhile, a new 50 Cent song, "I Get It In," debuted Monday on New York radio station Hot 97. Its parent album, "Before I Self Destruct," was originally due Dec. 9 but was delayed while the rapper continued recording. An Interscope spokesperson was unable to confirm a rumored Feb. 3 release date.

An earlier single "Get Up," stalled last year at No. 23 on Billboard's Hot R&B/Hip-Hop Songs chart. 50 Cent's last album, "Curtis," peaked at No. 2 in September 2007.
