Licensed music in in games in variety of ways. They can be used in trailers, they can be part of the in game soundtrack or maybe they're just being used as ambient sound. Either way, we sometimes find that song that we simply can't be satisfied to hear only in relation to the game, we need to be able to listen to them at any time. And this here is the thread to talk about those songs.
For me, a few I've found was:
You Think I Ain't Worth A Dollar, But I Feel Like A Millionaire - Queens of the Stoneage, from the intro cutscene to Jak X.
This Is The New Shit - Marilyn Manson, from the "Violence" trailer for Dragon Age Origins.
Alone And Forsaken - Hank Williams, from one of the trailers for The Last of Us.
Sleepyhead - Passion Pit, Reveal trailer for Little Big Planet 2.
