Online karaoke firm PureSolo has nabbed its biggest licence yet: Elvis Presley. Its latest app is Sing With The King, which invites people to “release your inner Elvis”. That means picking a track from The King’s back catalogue, singing along with on-screen lyrics and recording and sharing a music video. The app is free to download, but makes its money from in-app purchases. The iPhone and iPad app’s release follows the launch of a stable of similar apps by PureSolo including one for British singer Lisa Stansfield, and musical Annie.
