Produced by London on da Track, the foundation of “Come Thru” was built on Usher’s 1997 hit “You Make Me Wanna,” which made him the natural choice for this special guest turn. Jermaine Dupri, who co-wrote the original version, also pops up in the video. The highly infectious love song is the second official single from Walker’s history-making debut, Over It, which debuted at #2 on the Billboard Hot 200 last fall and remains in the Top 10.
