Just started to dip my toe into the water with these but it seems like there is hundreds of thousands of the buggers.
Every one you go on links to twenty others.

Can anyone point me towards the cream of the crop?
Preferably ones that focus on more alternative music rather than chart based stuff.

Cheers in anticipation.

Hype machine - something like this, collects music from all sorts of blogs from the internet and puts them onto one website for you to explore.

This is a good site for quality live recordings [mostly 70s & 80s rock] , usually in lossless format [as opposed to mp3] http://qualitybootz.blogspot.com/
