Sometimes 140-characters just isn't enough to get a message across, which is why Twitter teamed up with SoundCloud to bring audio to tweets yesterday.

Called an "Audio Card," Twitter plays audio when you click on a tweet from 60 select Twitter members including Coldplay (@coldplay), NASA (@nasa), This American Life (@thisamerlife), Zeds Dead (@whoszed), Steve Aoki (@steveaoki), David Guetta (@davidguetta) and The White House (@whitehouse). They began playing audio in their tweets yesterday.

A list of the Twitter users using audo reportedly will be listed soon on @TwitterMusic.

Within the next few weeks, Twitter will allow anyone with a SoundCloud account to play audio from their tweets, reports PC Magazine. 

The company projects that this feature will be especially attractive to musicians. 

"We're just beginning to test the Audio Card and plan to make it available to more partners and creators in the future so that many more musical artists and creators will be able to share exclusive, in-the-moment audio to millions of listeners on Twitter," says Twitter in a blog post.

Twitter, a social media avenue which was always dominated by words, is likely adding this audio component to compete with its competitors.

"We're excited to be working with Twitter to be the platform that's making audio cards available to everyone, from global superstars to bedroom beatmakers," Alexis Giles, director of SoundCloud business development and platform, wrote in a blog post. "It's just one more way that we're collaborating with all kinds of partners to build the best creator tools for you."
