This is a nearly impossible task when you have almost 12,000 songs.
I don't listen to half of it, but I always tell myself I will. It's a music addict's worst problem. However, I did get rid of roughly 200 songs. (I didn't try very hard, though.)
Plus, I have my sister's iTunes (after I lost mine) and some of the files aren't "authorized" for my computer, so I have to get rid of those, too.
The worst part is, I have about 400 to get back. No, probably almost 500 (considering I created less work for myself by using "Entire Album" rather than typing all the songs on the album when scribing my previous iTunes).
Even if I were a millionaire, I wouldn't have enough money to get all the music I wanted. Plus, finding bands with free downloads on their websites doesn't help at all, either! (Mostly because they give you a song or two then you find out they have an album or three and you just keep adding to your iTunes wishlist...)
Oh, yes, and then there's Spotify. When it first came out, I downloaded it because my mom sent me a request, but I didn't use it. Now it's become a bad habit. Find a band on Facebook, check Spotify and iTunes. If I had all my current songs on iTunes synced to Spotify, I'd never use iTunes again. (Actually I would because there's still a lot not on Spotify, but you get my drift.)
It's a good thing I'm young and have my whole life ahead of me - considering life doesn't become cruel and have a meteor hit me or some other weird tragic occurance. (:
As soon as I'm done getting rid of all the music I don't listen to, I'll be sure to post how much I got rid of. Hakuna matata.
