I like music.

I have been having an ongoing discussion with one of my peers about music. We were listening to a radio talk show and the crew got to bring in their three favorite songs. Of course, they were all songs that had been played on the radio before, and they were safe to play in public ears. It got me thinking about my three favorite songs, or lack thereof.
I feel it would be about impossible to pick three songs that I consider superior to all of the other music in my life. Taste changes, moods change, and it's hard not to get tired of songs, albums, bands even. I listen to different music depending on what kind of day it is outside. They would have to be timeless and able to stretch across changing attitudes. They would have to be songs that you are always ready to hear.
I honestly don't think I could do it. I was singing Steely Dan in the shower, listening to Tool on my way to school, and fell asleep last night to a mix of hits from the '90s. It's sunny out today so I might listen to some rap. I add and delete music from my iPod all the time. I can't sit still when it comes to music. I'd have to say there are only two groups that I've really stayed faithful to for the past couple of years, and they quit making music. What happens when I've overplayed the collection? On top of that there's plenty of music that I wouldn't listen to myself, but my friends and I do. I have good memories with them, and they mean a lot to me.
So in order to pick three songs I would consider my favorites, I would have to add subcategories. A tree view of all the criteria it takes to make a favorite song. If they asked me on a rainy monday I could navigate my way through the list to find songs that cross in the "rain" and "monday" branches. Then of course narrow it down by my mood, and what's been happening in my life. I think that is the only successful way that I could make a list of favorites.
