Rapper Jin recently celebrated his 26th birthday... and seven years in the music business. All growns up. The former RuffRyders recording artist and world reknown freestyle battle veteran has come a long way since those seven straight victories on BET's Freestyle Friday.

Last week, to commemorate the occasion, Jin premiered a new track, "Happy Birthday." You can hear the song exclusive on Jin's MySpace page. Consider it a taste of what's to come on his upcoming project, Birthdays, Funerals and Things In Between.

Jin is also working on a tribute track dedicated to the victims of last month's devastating earthquake in Sichuan, China. Hopefully, it'll serve to create awareness about the tragedy and the need for further aid.
