If you immediately recognize DJBooth newcomer Khalil’s new single Girlfriend Ringtone, I don’t know whether to be impressed by your encyclopedic memory, or a little worried that you spend too much time on the Booth. (Naw, you can never spend too much time in the Booth.) Let me cut to the chase. While the sparkling production from Sean Garrett and L.O.S. da Maestro was originally slated for Garrett’s Turbo 919 album, the song’s since found its way into Khalil’s capable hands; hands which have crafted Girlfriend Ringtone into a hit. Vocally the young Def Jam crooner walks the same well tread ground of the Marios and Chris Browns before him, and does so with skill, laying down a pop-infused ode to young love (and I mean like 15-years-old “young”). While I can only assume Khalil’s debut album Hot Like Summer will drop, you know, this summer, it technically has no release date, so in the meantime fans will have to content themselves with making Girlfriend Ringtone their ringtone.
