The Planet's 1980 LP Goon Hilly Down and 1981 LP Spot was released on CD in Japan in 2018 with five bonus tracks each. Some are unreleased, but some vinyls tracks are still missing.
Both albums are also available digitally, but the CDs contain more tracks than the digital album. Also you miss out the booklet of course.
(Why are digital booklets still so rare??)
