Use online music
I love music. It is another one of those things that can add beauty to my day. A few months ago, I signed up for Pandora and I've come to love it. They have what they call the Music Genome Project that categorizes music based on a number of factors so when you add a song or artist you like, they play similar music.
I have about a dozen artists and/or songs listed and can listen for hours to the music. If they play something I don't like, I give it a thumbs down and it goes away. Their system also then learns about what I do and don't like based on what I give thumbs down or a thumbs up to. It works great and best of all, there's no huge CD collection to track or search through. And, I can listen to it anywhere and anytime if I have a computer connection.
