Ending with some mean speed or thrash metal will definitely make for a very nice "final boss" feeling. I know some guys who play in thrash metal bands, they'll certainly give us a piece of their music to use in game.
My suggestions:
- The Surfer Dude:
I love surf music, some friends of mine play in a Surf band, they will absolutely give us one of their tracks for the game:

- The proud Country rebel
Mainly because I'd like to have a setting where Eric can make full use of the infamous drunk mode and a scrapyard. A scrapyard with an old man and some dogs on it is always fun, isn't it?
- The Titanic Fiddler
We already discussed that, but way to present it again: One of the violin players that sank with the Titanic has also entered the nimbus with his fiddle in his hand - lots of sonar map ship finding and diving fun for all!
- The slightly confused Gentleman of Dodecaphonism
Just because twelve-tone music is so outrageously great. Go Arnold Schönberg!
