This app is a free version of TwitSong.
The difference with the paid version is that you can't play the app by itself or set the template when posting, but it has new features such as history.

Simply tap "Share" from the Widget in the notification area to share songs and podcasts you're listening to in the iOS music app with friends and acquaintances.

In addition to social networking services, you can also share messages, emails, and third party applications.

'My favourite and favourite song, the one that moves me to tears, the one I remember, the one I want to tell all my friends away. I'll also tell you how I feel about the song. Let's enjoy more and more music.

All you have to do is slyly pull it out of the notification area while listening to your favorite song.
It's easy to share.
