I love the music from year 2 as well, especially the music that plays in Maximino's Office. I think the song you are referring to is Hi-Tone Fandango, which plays outside the cafe. Great song..
Maybe, but my pick are:
-End Credits!!!! Excellent with Mexico and sad violin style! My, Micheal z Land is a genius!
-Outside Calavera cafe: Jazz-y!
-New LSA HQ
