Music brings people together, connects them. So it’s only natural that the music scene would move to a digital venue.

This month, music streaming giant Pandora reached 200 million users, 100 million of which registered in less than two years! Upon this achievement, founder Tim Westergren stated that “radio is changing,” and he couldn’t be more correct.

Pandora has yet to implement major social features, but Swedish streaming service Spotify has made a huge splash in the US market after a successful launch in June 2011. The service is heavily integrated with Facebook and Twitter, at one point requiring a Facebook log-in to create an account.

We’re guessing Twitter caught wind of Spotify’s success, since today marks the launch of the Twitter Music app, confirmed after longtime rumors (and Ryan Seacrest blabbing about it!). TechCrunch speculates that this weekend’s launch coinciding with the Coachella Music Festival is no coincidence and is on the lookout for marketing at the festival.

It’s rumored that Twitter Music will be split into four tabs: “Suggested,” which consists of music based on who you’re following; “#NowPlaying,” which features songs tweeted by your friends with that hashtag; “Popular,” which displays trending songs throughout Twitter; and “Emerging,” which shows up and coming new music.

Someone had better let MegaUpload’s Kim Dotcom know about Twitter’s big plans. His disembodied head made some big claims at this past SXSW in regards to music services – going so far as to claim he could take down iTunes.

Everywhere’s office playlist is a big deal, so we’re looking forward to trying out the new Twitter app! Check out some of our past 5:00 p.m. jam sessions here.
