Each year since 1973, a committee has come together to select songs for the Grammy Hall of Fame. These songs are selected because they are considered to be of historical significance. Songs, like in most Hall of Fame scenarios, must be at least 25 years old to be considered. The Grammy HOF currently houses songs such as "All Along The Watchtower" from The Jimi Hendrix Experience, "Free Bird" from Lynyrd Skynyrd, Pink Floyd's entire "Dark Side of the Moon" album, and a collection of Beethoven recordings. Well as of yesterday, Deep Purple's "Smoke on the Water" and Nirvana's "Smells Like Teen Spirit" will both be added. The songs will be the first inductions for both groups and will be officially be recognized at the Grammy Awards on February 12th. You can read more of this years inductees HERE.
