TwentyForSeven may sound familiar -- the band has opened for Gym Class Heroes, Sum 41 and Parachute, and you may recognize them from E!'s 'Opening Act.' Now, dropping their debut single 'All I Ever Wanted,' they're out to make them household names of themselves.

The single boasts a crazy catchy "oh oh whoa" hook reminiscent of a more upbeat Kings of Leon 'Use Somebody' refrain. Singer Rajiv Dhall pleads with a girl he regrets losing, "I wonder if I'm too late / What if backing down was a mistake / Would I be a fool to let you go / Think I should let you know / That all I ever wanted was you."

From the sounds of it, Dhall more than overcame his confidence and vocal issues from their television debut.

Aside from an impressive first single, the band boasts some seriously nice numbers: 2.5 million views on YouTube with over 22,000 channel subscribers. The band often performs covers for their channel, including renditions of One Direction's 'Little Things,' Maroon 5's 'Payphone' and Olly Murs' 'Dance With Me Tonight.'

'All I Ever Wanted' is available on TwentyForSeven's debut EP, 'Forget the World.' While you may indeed forget the world, you probably still won't forget the hook to this song.
