Seen on Scripting News: Google Music Search (see also announcement on the Google Blog). Pretty slick way to organize information about music from around the web. Included: links to album art, organized list of songs, buy links, lyrics (though perhaps not for long). Probably never included: links to MP3 files or torrents.
I wonder what their source of data is, btw. Artists on independent sites like CDBaby aren’t picked up (no Suspicious Cheese Lords, Justin Rosolino’s first album is present but not his latest), but obscure long dead bands like Annabouboula are.
