The inaugrual Geoff & Betty mixtape. We found Mixwit via Boggins whose own mixtape is very enjoyable.
Mixwit is a great idea but doomed to failure as it relies on the mp3s being permanently available on the internet. Of course the buggers are always disappearing so that in time there'll be nothing left on this tape. There will be the sound of silence which is probably how it should be.
p.s. If any of the songs are no longer there, skip till the next one.
