For some reason, Ty Dolla $ign and rapper Baby Bash feel like an especially complementary duo, as slick sweet-talkers with particularly smooth sing-song approach to the pop jugular. "Low Key" isn't a bad description for the way the song sidles easily against your eardrums. Baby Bash has struggled to match the mainstream success he hit with "Suga Suga" and "Baby I'm Back." (We'll pretend "Cyclone" didn't happen—even if you like it, you have to admit it feels more like a T-Pain single and doesn't exactly play to Bash's strengths). "Low Key," though, is right in the rapper's sweet spot, and with Ty Dolla sending his own singles up the flagpole, it's as good a time as any for a comeback.
