Google just keeps getting more useful...
Search for "James Brown" and you'll see a link, in the "Web / Video / News" bar, for "Music", which is the results of Google's "Music Search": Google Search: james brown.
Then you'll get to see all (?) of his albums and songs. The album links bring up lists of all the tracks on the album, which in turn link to info about each particular song, including links to cover versions, lyrics, etc..
It's much faster and cleaner than AllMusic, if you're just looking up songs on albums. But, they don't have the depth that AllMusic does (neither "Robyn Hitchcock" nor "Sea and Cake" for example, bring up a "Music" link). It's a work in progress, I assume.
Still, pretty cool.
So, when does the google search engine become self-aware and turn into Skynet? I say in about five years.
let’s just hope there’s a big, red “Kill” switch somewhere in the CEO’s office.
