‘Let Go - Avril Lavigne’ DataPlay disk (2002)

“DataPlay was an optical disk format for audio and data storage, introduced in 2002 (the company went out of business later that same year). It used a very small 32mm diameter disc with a capacity of 500 MB enclosed in a protective cartridge. DataPlay was used for portable music playback, and a small number of pre-recorded albums were released. They were recordable, but only write-once like CD-R.”
