Jam On is members-only den music that was first released on August 9, 2011, as one of the default den music choices for members. On October 27, 2011, it was removed as a default music choice and was sold at the Music Shop instead.
The cover art for Jam On shows a record on a spindle with an orange paw, which has sharp claws, covering up one side.
This music has an electronic melody with an upbeat rhythm. It features heavy use of synthetic electronic instruments with occasional record-scratching and vocal cheers.
- This was the music played at the April Fools' Party, but the name "Jam On" has no resemblance to April Fools.
