Hmm, the title of this post could be misleading, I don't have any songs for free. I got the idea of "free" songs from Jim Ladd of KLOS (LA classic rock radio).
Each Friday night Jim has a show called Theme of Consciousness where he suggests a word then the listeners come up with songs that have that word in the title and those song make up his set list for the evening. Jim is known for playing some very deep cuts that are rarely played on mainstream radio.
So, for fun, lets see what we can come up with to create our own "Free" playlist. I will start off with a couple obvious ones, it can be the word free or any word that contains free:
Free Falling, Tom Petty
Free Bird, Lynrd Skynrd
Freedom, Rage Against the Machine
Philadelphia Freedom, Elton John
Free Man in Paris, Joni Mitchell
