Twitter has began letting people listen to music and other audio by clicking on tweets. The new Twitter Audio Card feature, launched on Thursday in partnerships with SoundCloud and Apple's iTunes store, will allow users to stream audio live from the Twitter app.

Audio Card works on mobile devices powered by Android or Apple software.

"We're just beginning to test the Audio Card and plan to make it available to more partners and creators in the future," the San Francisco-based firm said in a blog post.

"Many more musical artists and creators will be able to share exclusive, in-the-moment audio to millions of listeners on Twitter," it added, without saying when new users would join.

For starters, Twitter has promised audio from SoundCloud's partners, which include such diverse sources as NASA, the Washington Post, CNN, David Guetta, Coldplay and Warner Music.

Twitter said that it offers musicians a chance to post exclusive clips.
