Simon Mayo has the ultimate music question - and here's your chance to answer it!
In November and December 2005 thousands of you helped us select your Ultimate Top Ten in the run up to the Ultimate Music Year on 2nd January 2006.
We want to answer the ultimate question; Which of the last 50 years has been the best for music, from a Britsh perspective, since the birth of Rock 'n Roll in 1955?
Check out the top ten to see if your ultimate year made it in, and find out what you voted as the ultimate year in music. Simon Mayo and his guests Andrew Collins and Neil McCormick battled it out in a three-hour spectacular in a special Bank Holiday programme to help you make up your mind.
We considered singles, albums, live performances, iconic music events and artists, music movements and watersheds - landmarks which changed music forever across a range of Radio 2 genres and styles.
