hi guys,

i'm seeing a few spotify invites going out, looking people over the shoulder, and i thought i'd take this opportunity to say that i.. love.. spotify.

i've been on your waiting list ever since XXXXXXXXXXXX mentioned you, maybe 18 months ago. i would _SO_ love an invite. i've been told the only way to get an invite is to buy you guys beer. listen, i'll have it fed-exed into your office, A-S-A-P!

look, it's me, doing an elaborate handstand:
