His third album Wonderland was launched on December 28, 2008. Wonderland's music style marked a leave from his previous albums. It featured funkier tunes rather than the slower ballads of his previous albums.

Khalil's fourth album Orange Moon was released on December 19, 2008. It featured slower, more conventional love ballads. Khalil had said that this album Orange Moon was meant to be a more romantic album, with the songs revolving around the theme of love.

A cover album titled Timeless followed on August 11, 2009. It featured songs by various singers whom, according to him, influenced his music. Among the songs are "You are the Sunshine of My Life" by his childhood idol Stevie Wonder and "Bad" by Michael Jackson.

Although based in Hong Kong, Khalil's career and popularity was first established in Taiwan because his songs are sung in Mandarin rather than Cantonese. He has won numerous awards for his music in both Hong Kong and Taiwan to date.
