Two unreleased Mac Miller songs have arrived via Rostrum Records to celebrate the 10-year anniversary of his K.I.D.S. mixtape.

Released on Thursday (August 13), the deluxe version features new tracks “Ayye” and “Back in the Day” to extend the project to 18 songs in total. Speaking on Twitter, the label said, “K.I.D.S. holds a special place in all of our hearts. We hope you enjoy celebrating this iconic mixtape with us!”

Both songs were recorded around the K.I.D.S. era, with lyrics about proving people wrong and taking his music further.

As he raps on “Ayye, “Too many people always thought I wouldn’t ever do shit/I’m ruinin’ my life and I’ll never get rich/Forever I’m this/Never goin’ back/Don’t fade to black/I’ma stain the map.”

Miller’s frequent collaborator E. Dan of ID Labs posted a tribute message on Instagram, saying, “I produced this one called ‘Ayye’. Love and miss my brother everyday and forever.”

The other song, “Back in the Day,” was produced by Will Brown.

K.I.D.S., which stands for Kickin’ Incredibly Dope Shit, was inspired by the 1995 coming-of-age movie of the same name. It was his fourth mixtape and featured notable tracks such as “Nikes on My Feet” and “Kool Aid & Frozen Pizza.”

The project hit streaming platforms for the first time in April after it was originally released as a free download on DatPiff a decade ago. It debuted at No. 112 on the Billboard 200 chart with roughly 9,000 total album equivalent units earned.

Rostrum released Miller’s first two albums Blue Slide Park and Watching Movies with the Sound Off, before the late rapper moved over to Warner Records in a deal reportedly worth $10 million. In addition to Miller, the Pittsburgh label is also known for its success with Wiz Khalifa.
