I'm wanting to use music from DOS games like Dungeon Master II, Stonekeep, Lands of Lore etc. for their medieval MIDI music to be used in a Heretic mod. Should I avoid this altogether because these songs are technically companies' property? Or does it slide by community standards to put in a text file giving credit to the original owners?
If it is acceptable to use them with credit, then how thorough should the credit be? Will it suffice just by naming the games that the songs came from? Should I go more detailed, and spell it out like:
Obviously this example is pretty heavy on the detail, but I wouldn't want to "under-credit" seeing as one reason I'm so concerned about giving proper credit is to not get myself into trouble with anyone, whether it be any existing companies over legalities (which a credit text probably wouldn't protect me from lol) or the Doom community for being a jerk who doesn't give credit well."Stonekeep, DOS (1995) by Interplay Entertainment; composed by Brian Luzietti and Richard Band"
I'm likely overthinking this.
TL;DR Is it acceptable to use music from old DOS games in a mod with credit given? If so, how thorough should I credit?
