Always tweeting? Love music? There's a hashtag for that.

The new Twitter #Music service (available at music.twitter.com and separate from the main microblogging site) will let the site's hundreds of millions of users find and listen to songs that are being talked about -- in 140 characters or less, of course -- on the social networking site. iPhone users can get the app through iTunes.

The #Music service shows users what's trending on Twitter and the groups you follow. There are four pages to #Music.

POPULAR shows what's trending across the site. "Never Should Have," from Glen Cove's Ashanti, was No. 3 for a while last week.

EMERGING offers "hidden talent found in tweets."

SUGGESTED hints at what artists you might like (you need to sign in for this).
