So basically load up your spotify libary or any other library for that matter, put that bad boy on shuffle then put the first 20 songs to go on into a handy spotify playlist for you all to share.
The thinking? A lot of spotify playlists seem to feature the same songs over and over and seem to be aimed specific at one audience, this adds the unpredictable element so you can discover more things or something like that or... shit.
Interludes may be skipped, so add 20 songs
One entry per artist, so you can skip duplicates *Optional*
If it's not avalible on spotify then don't count it
