Young Singer Sues Lil Wayne's Young Money -- 'Let Me Out!'

A 15-year-old singer has had it with Young Money and Lil Wayne and wants to jump ship ... and he's asking a court for help.

Torion Sellers claims in new legal docs -- obtained by TMZ -- he auditioned for Lil Wayne when he was only 13 and Wayne immediately saw what he called Torion's "amazing voice" and "God-given gift and talent."

According to the docs, Wayne signed Torion to Young Money and promised to record and release an album by Spring, 2012. But tick tock, tick tock ... still no album more than a year later.

Torion claims Wayne and company have abandoned him, and he wants out of the contract. He claims Young Money screwed up by forgetting to get court approval of the contract it signed with the kid, and on that basis Torion wants to 86 the deal.

Torion believes he will be snatched up by another record label, but no one will touch him until a judge rules the Young Money deal is invalid.
