That site is going to take time. My bro works on it in his spare time. In the mean time try this out.

search in google for "Free Video to Mp3 Converter"! You´ll go to sourceforge and after install this nice program you only must copy the link of your browser and klick convert ;)

someone sent this as a comment on one of my videos. When the site is up, i'll post up longer mixes.

Peace.
