Are gamerips legal?

I'm not a specialist in the field of copyright law and can't give you a precise definition. Generally speaking, music tracks are intellectual property and are subject to copyright unless they are too old and have been transferred into the public domain (which is likely to take some time for video games). This is not a problem with OSTs, as you purchase a copy or pay to stream the album for private use.

Gamerips, on the other hand, are the external and unauthorized extraction of files from a medium. However, and here I am on the side of conservatism, the lack of effort on the part of artists or publishers can lead to music, i.e. art, being irretrievably lost.

I don't want to start a fundamental discussion at this point, I don't want to judge whether the creators have the right to determine the context in which their work may be used (for example, only as part of the gaming experience). In my opinion, everyone should have the freedom to experience a piece of music outside of a game.
