I used to frequent a music forum and send out music mix CD's of your favourite music. Asked how many people wanted to participate, then send out a selection of your favourite songs to the next person on the list. While this would be less practical here the next idea for those members that wish to participate get listed and then in descending order after enough participated. Post your favourite music track listing you'd be proud to have in your car CD, playlist, in the background at home that impacted your life. And compile the list here or pm the person with your choices and why you like the songs you like using youtube and the like.
Anyone interested in the idea?
A typical CD would have 10-15 tracks so you would be choosing your top 10-15 songs.
