That's curious. Would that mean they changed the offending track(s) in the vinyl release, and maybe tape release?
Have a look at the Japanese Wikipedia page for Bomb Jack:
https://ja.wikipedia.org/wiki/ボンジャック
Google's translation says:
The first song is the ending theme of the anime " Aunt Spoon " ( 1983 - 1984 ) " kittens of the apple forest " (1983, composition: Tomomi Kyohei [2] ), the second song is the Beatles ' Lady Madonna 1968 , composition: Lennon - McCartney ) has been used, the third song is the original song of the game. In the following rounds, these three songs are repeated. Furthermore, looking at the instructor card and promotional leaflet, I understand that it was officially accepted by JASRAC rather than unauthorized use. However, as described later, BGM was changed or deleted in many models due to the issue of rights. TECMO games · chronicle (SRIN - 1104) "released on June 7, 2014, as well as BGM collection" TECMO GAME MUSIC (28 XA - 95) "released on September 25, 1986 It is recorded including copyright tune.
The use of these copyrighted sounds could be the reason for the recall, if there ever was one. Not sure what to make of the last sentence, seems that SRIN-1104 also uses the copyrighted sounds, but maybe by 2014 they were able to settle the issue? That leaves the question of what's inside the vinyl and tape releases.
Regarding SRIN-1104, looking at the notes at the bottom

Seems the Beatles sound was acknowledged properly in this release, along with 2 other copyrighted sounds.
So I'd say the offending tracks are
BOMB JACK BGM 2, which uses the staff roll fromt the anime "Mrs. Pepper Pot"

2 more tracks use copyrighted/existing stuff:
Track 65 of TECMO CUP uses Jerusalem by Hubert Parry

Track 68 of TECMO CUP uses Perfect Kiss ©by BE MUSIC, which should be this 1985 song

Is TECMO CUP from SRIN-1104 the same as WORLD CUP from 28XA-95? It's all so confusing I want to turn off my PC right now.
And why isn't Mrs. Pepper Pot NOT mentioned in the copyrights of the SRIN-1104 release? One more reason to switch off my PC.
