Cymbal, and many have called it the "Instagram of Music" because of its less-is-more user interface.
Cymbal describes itself as "music powered by friends, not algorithms." That's because users are allowed to share just one song at a time along with album art.
The whole idea is that the user gets to post that one song that's most important in their life at that moment.
Like Instagram, Cymbal uses a home feed, personal profile, followers, likes, comments, hashtags and tags.
You can share tracks from Soundcloud or Spotify, and since it was created from the ground up as an iOS app (an Android version is coming), it's perfectly at home where more and more do their listening - via the phone.
There's less than a million users at the moment, but the app seems to be coming on strong, so look out for more about Cymbal in the future.
