Of all the artists featured on this list, no one’s stock has risen quite as quickly as Raleigh Ritchie‘s. The 24 year-old singer/actor got his start in “the biz” back in 2007 after landing a small role on the British soap-opera, Doctors. A few roles later and Ritchie, aka Jacob Anderson, has found himself the talk of the town following his Grey Worm performance on HBO’s smash-hit, Game of Thrones. Hoping he can translate this on-screen success into his music, Anderson has churned out three highly-accessible EPs under his alias. Of those three releases, only one of his songs has landed on the charts. But if his newest single, “Birthday Girl,” is any indication of what’s to come, this long overlooked songwriter will be climbing the charts very shortly.
