Here's how it works. I post a band and a song of theirs, say:
White Stripes - It's True that We Love One Another
The next person to post then posts a song that contains a word of the song above. Therefore the next song could be
Pink Floyd - Another Brick In The Wall
and a possible next would be:
Michael Jackson - Off the wall
Now I might be a thick auld cunt but ME and MEO are not the same word in my language, so away and shake yer cocktails
