So I've created this playlist:
http://open.spotify.com/user/paulhawkins/playlist/2Qc4SKKC7rnFmUDqfKAVPe

It's got 15 songs on it, each connected to the next by at least one word in the song name, album name or band name (the first is from REM's "Out of Time" and the second is Blur's "Out of time" then, 'cos that's from Think Tank, the third has "think" in the title and so forth.

Anyway, if anyone's interested the challenge is to keep it going following only two rules:

a) you know the song you add (so don't just add one by searching and picking out something you've never heard)

b) You add songs you at least quite enjoy listening to.

So yeah, give it a go if this appeals...
