Only half-bloods allowed! discussion

Ok, well I was wondering what songs remind you of the couples in PJO and HoO. An example, (the only one I can really think of...) Captains and Cruise Ships by Owl City linked here: http://www.youtube.com/watch?v=JB7HqM... It kind reminds me of Percy and Annabeth because the whole ocean type theme and because they are apart... (I BLAME YOU HERA!) But, yah, can any of you think of any other songs?
