I'd argue so! The music producers made their money, the original company made their money. The game isn't sold or updated anymore. Music was part of the game, it stays part of the game. Noone is profiting from it (with this clause, ie: non-commercial is the main thing for community/public domain takeover). For the music and similar assets the clause is usually already clear even nowadys, as long as the music is being displayed alongside the game, it's fine (that's how 99% of the music copyright works nowadays with modern games re streaming, unless the music company is backwards because they are greedy).

We need to kill indefinite (or even long) copyright and the music industry has been one of the worst offenders.
