Startup Idea : Cloud Music App

Being able to share music with a friend group on the cloud. The main idea would be that you can share songs with a group whenever you are listening to something you think others may enjoy. You have the availability to up-vote, down-vote, comment and rearrange playlists. It would be awesome to be able to hear a song, ask siri what the song is, and then share it to the cloud so everyone could listen to the new song. Similar to spotify however it would enable more interactions and the song could be added from any software
