Developed with the Berlin-based audio-streaming service SoundCloud, the Twitter "audio card" lets users discover and listen to audio directly on both iOS and Android devices.

Twitter hopes it will attract more musicians to the service.

"We are 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," it said in a blog post.

“Throughout your listening experience, you can dock the Audio Card and keep listening as you continue to browse inside the Twitter app," it added.

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, Daily Mail reported.
