Kidz Bop 6 is the sixth album in the main Kidz Bop series and tenth in the series overall. It features several pop hits from early 2004, including three dance remixes of songs from previous Kidz Bop albums. This is the first album to only have the traditional one-disc, 18-song CD version rather than the special two-disc, cassette 30-song version.
Heather Phares of Allmusic calls the album one of the weakest installments in the series. The songs in this collection are "short on universally acclaimed singles" with the closest being Jet's "Are You Gonna Be My Girl?". That track is "one of the more kid-appropriate songs here", but like all the Kidz Bop albums, there are "songs that work surprisingly well with kids singing along to them ('Are You Gonna Be My Girl', 'Ocean Avenue') and "songs that don't work at all with kids singing along to them ('Toxic', 'With You', 'My Immortal')".
