JAMM lets you share any song using any messaging app, and automatically remembers what music you have exchanged with each of your friends.
Use the JAMM sharing option when sending links from YouTube with any messaging app you like. The JAMM app will remember which songs you have shared. Once your friend clicks the link you sent, the JAMM app will remember which friend you shared it with.
View your "music conversation" with each of your friends in the JAMM app, showing all of the songs you have sent back and forth. Let your friends know what you think of the songs they sent you with a variety of fun reactions.
