Okay, I can explain this one. See, there's this song I just adore by Full Force called "Unselfish Lover". Of course the combination of having Cars on my mind, reading fanfic, and currently being 2 in the morning gels into one big mess which results in this song reminding me of slash. :P

But still though! Listen to the lyrics up until that point! To me the song sounds like potential for fic inspiration. Which is ironic since I can't write, but you get me. :)
