Of those options: Metal Gear Solid. In my mind, the MGS series have several songs that work outside the context of the game that are still part of the game, while the others don't- as far as I can remember, Kingdom Hearts' songs are either intro pop songs, or BGM tied to different areas of the game world.
Now when I think about it, it's a tie between Halo and MGS. Portal, however, has -ONE- song. It's a good song, a real ear worm. But that's it.
I've not played either other options, so I can't say anything, but of the three above, it ties with MGS and Halo.
