Just stumbled upon another fine mashup (thanks Caschy!):
Whenever I see something like that I quickly fire up EVOM and download a copy – these videos disappear as quickly as they appear.
EVOM makes it really easy to download a copy to iTunes. You can even chose to get ‘just’ the audio of the track (which I did here).
Now all I need is a Chrome extension “Send to EVOM” ;)
