Musi lets you build an entire streaming music library, completely for free

Musi for iPhone is a streaming music app that lets you build a music library that costs you literally nothing, with the help of YouTube. When you search through Musi, it's basically like searching YouTube for music. The only difference is that Musi only streams the audio portion.

You can start by searching for your favorite artists and adding the tracks you like. They are then added to your main library. From there you can sort songs into playlists however you'd like. Playlists are unlimited so you can create and manage them however you want. For many people, this may be a way to create albums. This is the only downside of Musi. Since it's simply searching YouTube for tracks, you need to add tracks one by one. It's not a huge deal if you don't mind creating playlists for artists or aren't the type of person that downloads entire albums anyways.

Musi also has support for AirPlay so you can stream anything you want to any AirPlay enabled device. Along with that you get background streaming as well so you can close out the app and continue doing something else while Musi continues to serve up tracks in the background.

Obviously Musi isn't an all-in-one music solution since it won't work if you don't have an internet connection, but it's a super convenient ones for folks like me who are finicky with music. I have a nasty habit of only listening to things for a few weeks and then never really returning to them again. For stuff like that, Musi is perfect since I'm not spending money on songs and tracks I won't even want to listen to in a few weeks.

If you give Musi a try, let us know what you think of it in the comments! Could you see yourself using it for music discovery and then only purchasing the albums and tracks you want to keep forever?

  • Great app! Sometimes I hear a song and just like to hear it again to see if I really like it. As long as I have an internet connection I can use it. This is a very little inconvenience to pay for an app that not only free but very useful. I thank the developer (s). Everyday I am amazed of what developers can come up with. Happy New Year to all!!
  • Excellent app. Was waiting for something that can stream only audio from youtbe. This does exacty that. Any options to increase the audio quality. I am listening to a 1080P video that has pretty good audio, but audio quality and volume is a bit low. I would not mind paying if these feaures are added. Good job guys.
  • I use jasmine and love it. How does this compare? Sent from the iMore App
  • Nice find. Perfect for those songs you aren't sure if you want/like the song or not. Would love to see some shazam integration. That would be the ideal music discovery tool. Sent from the iMore App
  • Thanks for the review on this app! Sent from the iMore App
  • I know that you mentioned that it will only stream the audio part of the video but won't it eat up more of your bandwidth since it's using YouTube for searching and streaming compared to just listening from the usual streaming services.
    Still I think this is great to those who are just starting to build their own playlist.
  • I tried this app. Not bad, i would say. one more to add is ArkMC. It ai a streaming app that allows to stream not only audio, but also videos and images. It has integration with youtube, too!
