You
can't take music from one game and place in another for distribution, unless the creator of the music/game has given explicit permission that this is allowed, particularly a game like Medal of Honor. In the case of this game, you would need to contact the company (companies) involved (Dreamworks Interactive/Electronic Arts), not seek a
legal answer here.
There are plenty of sites that have music available that can be used in your developments. For example, an
excellent site is
Incompetech and there is a wide range of music. Be certain to read the FAQ- it is very clear on what can be done. Same with other sites.
And for the record, age of the game is
not a factor. Copyright is copyright.
There's no problem that can't be solved without applying a little scripting.
