I love so many songs and so many different genres of music that I made a decision:

Favorite Song:
Thru the Eyes of a Ruby, by The Smashing Pumpkins

Second Favorite Song:
In Your Wildest Dreams, by The Moody Blues

I don't care if a better song comes out that I think is way cooler, that I could listen to forever.
Those are my two favorite songs. The decision is final. Now I never have to worry about it ever again.
