Sort of, yes. I chose Beyond the Sea for the Armor-Piercing Rounds because one of the first trailers for BioShock featured a fight with a Bouncer to the tune of the song, for example. The rest of the pairs are more or less linked as well, so Pop Goes the Weasel would be the appropriate tune for "popping" multiple Splicers, Welcome to Rapture's arpeggios are reminescent of shivering, etc.
