This 'game' (if you would like to put it) is fairly simple and straightforward. Basically, one person posts a link to a song (preferably using YouTube), then another person listens to said song and gives it a rating out of ten and leaves a song to be rated and the cycle repeats. Do not rate a song that was posted by you. Also, if two people rate a song at the same time, then whoever posted first is the one that has to be reviewed. This has worked very well on another forum I am a member of and has accumulated almost 500 pages and nearly 10,000 posts.
I'll get the ball rolling with:
Norwegian Wood (This Bird Has Flown), The Beatles
