Half Way There....

I find it difficult to manage my iPod and music. Thanks to some recent acquisitions, I have over 20,000 songs to choose from. The problem is that I can only fit about quarter on my iPod so I have to do a lot of picking and choosing. I will admit to being a film junkie but when it comes to music I am strictly an innocent bystander. I know what I like and don't like (mood by mood) but I have real difficulty remembering song names and artists so wading through tens of thousands of songs is difficult for me to find what I am looking for. It also doesn't help that I have such a wide taste in music and can't really decide on a single genre to listen to. Combine that with slight music ADD and well... you get the picture. So I ask the world "Any advice?" Help a boy out, oh and if you have an artist to recommend... let me know that too.
