Sentimental Value?

Okay, so this has been bothering me for ages now. What do you do with the music in your library that you've accumulated but dont listen to? I have many soundtracks that i do not listen to but i cant bring myself to delete them! this goes for my sister's music i dont lsten to, also!
for example:
the wicked soundtrack
songs from lion king, hercules, etc.
hairspray? Sweeney todd? Rent?

I dont want to delete this music because i COULD want to lsten to it in the future, right? but i do NOT want it on my ipod/the shuffle songs.
BUT i dont wanna go through and create a huge playlist with the library that i WANT because i would forget to add songs to the huge library playlist.

Well, thats just one predicament thats been bothering me. That and the whole "i" button on my keyboard being a SPAZ and coming off every other time i use it. VERY annoying if you've never experienced it. when my "shift" broke, at least i had a spare. this 'i' sucks.
