Yes, someone made a SWTOR hip-hop song already
So you have the Star Wars: The Old Republic Collector's Edition, the lunchbox, the action figures, the pajamas, and the bedsheets*. The game launched 12 hours ago and you have two level 50s. What else would you possibly need to make your life complete? How about a hip-hop song based on your new obsession?
Yep, there's now a hip-hop song all about SWTOR entitled Cold Republic, created by the already-established hip-hop artist Richie Branson. It seems Richie enjoys playing his Empire character Kazen on the Ven Zallow RP-PVP so much that he stopped playing just long enough to write and record a song about it.
According to his website, he plans to create more SWTOR-related songs, using samples from the game itself.
