Tinny, will forever be remembered as the artist who broke into the predominantly Twi dominated hiplife music with his fast rhyming raps and punch lines in Ga.

His distinct flow and ability to manipulate beats makes him a delight to listen to, whether on his own track or as a guest artist. His self-professed sex appeal and claim to be Aletse makes him controversial as well as exciting.

In 2008, Tinny had the chance to record a single with Ja Rule when Ja Rule was in Ghana to perform during the 2008 Ghana Music Awards. The single is set to be released soon.
