Day 01 - Your favorite song
This is easy. "Soul to Squeeze" by Red Hot Chili Peppers.This had been my favorite song for at least 5 years. It's so beautiful and amazing. It appears on the Coneheads (one of my favorite movies) soundtrack. And also on their greatest hits album.
The video is incredible too. However, John Frusciante isn't in it because at that time, he was kicked out of the band because of his excessive drug use.
I love the video of it too. Truly a masterpiece, as are most of their videos.
