On a recent tour in the UK, the singer Ne-Yo signed a British singer/songwriter, Sonna Rele to his Universal Motown Records label, after discovering her on YouTube.

Ne-Yo says being active on social networking platforms is important, but having high numbers isn't an issue for him when he's talent searching.

He's also signed singer/songwriter Conor Maynard, who says having a strong social media presence helped his career.
