He is best known for his songwriting work for numerous releases by American singer Trey Songz, including his 2009 single "Bottoms Up", which peaked at number six on the Billboard Hot 100.

Following its success, Scales has since been credited on albums by Justin Bieber, Jamie Foxx, Dr. Dre, Plies, Jacquees, Maejor, Queen Naija, and Sean Paul, among others.

The song peaked at number 66 on the Billboard Hot 100, which led to Scales' long-term deal to write, produce, and develop talent with Atlantic Records funding.

Record executive Lyor Cohen, North American chairman and CEO of Warner Music Group, specifically constructed the deal to mimic the success of the Motown-era with Scales at the helm.

Scales also penned Songz' singles "Bottoms Up," "Love Faces," "Say Aah," "Yo Side of the Bed," and "LOL :-)," which he wrote and produced, along with several other album tracks.
