You guys are in the music industry so think of how many times a tune has appeared on adverts or other media presentations.
I see your point, but let me make an analogy :D
What about Sean Connery being asked to act the leadrole in The Rock. Sounds fair, rite? Now.. what would you think if his character was called 'James Bond'?
What you're referring to is more like library-music, or stock-music. And yes, they're often used in corporate video, commercials etc. and it doesn't really matter there as it's not really as much part of the whole thing as original music is, in a movie or game.
