"Ayo!" is a song by American recording artist Mýa. It served as a promotional single for her fourth studio album Liberation (2007) and featured Washington D.C. native DJ Kool. Initially, released as the first intended single from Liberation however though the single failed to pick up as Harrison was going through transitioning from former label Interscope to her current label Universal Motown. The song was written and composed by Harrison, Christopher \u201cDeep\u201d Henderson and Charlie Smalls. It sampled an interpolation from the composition He's the Wizard written by Charlie Smalls.
The song received generally positive reviews from contemporary music critics comparing the song's production to TLC's classic \u201890s album "CrazySexyCool". Ayo! became a minor hit on Billboard's Hot R&B/Hip-Hop Songs chart peaking at number seventy. No music video was released for the song due to it not being picked up as a single.
