Not sure if this has been done on this forum, but anyway, couldn't be simpler.
1) Grab your iPod or preferred medium of playing music.
2) Put ALL of the said device onto shuffle/random (no missing out that embarrassing record).
3) List the first 10 songs that come up in order.
4) Highlight in bold your favourite of the selection.
5) Next person comments on your list to make it interactive and initiate banter/mocking of the above persons list. Comment on your favourite song from the list, simply state that you've never heard any of that junk or ridicule the fact that a 20+ male has a Britney Spears song on their iPod.
Anyway I'll start us off, enjoy!
