R&B's newest starlet is aiming high. "2 On," featuring Schoolboy Q, the lead single from Tinashe's forthcoming debut album, "Aquarius," is growing steadily on radio, moving 24-21 in just its fourth week on Billboard's Rhythmic chart dated May 10 and 31-29 in its fifth week on R&B/Hip-Hop, both new peaks. The on-air support is translating to rising sales as well, with the song moving 17-14 on R&B Digital Songs thanks to a 22 percent weekly gain to 11,000 downloads, according to Nielsen SoundScan. It has sold 65,000 total. But that's not enough for Tinashe.
