Alternative to allmusic.com?

I've used allmusic.com to find out information about musicians, albums and songs for years. It's always been a clunky, slow web site. The most annoying thing was that they used Javascript instead of a href for links, so you couldn't open another window to explore something else later, couldn't bookmark individual pages and it was difficult to send a link to a friend.

Well now it's got even worse. Their recent "upgrade" to the site has made it slower and even dodgier. They now state that they only support Internet Exploder on Windows platforms. Outrageous!

So does anyone know of an alternative that is as good and comprehensive as allmusic.com for information about artists? I can imagine some online project like IMDB for music would be great. A Wiki type thing would be perfect, with strict templates.
