Add an Amazon Music channel
My proposal is to set up a channel similar to AlwaysOn that broadcasts the top 100 purchased songs on Amazon Music. A countdown of the top ranked daily playlist could be cycled through and, for those who have Twitch Prime, free daily song requests of any Amazon Music song. Another possibility path to take would be hourly give aways of a few songs worth of Amazon Music gift certificates. With both being used, I feel that the requests will get the people into the channel, and the give aways will keep them listening longer. And as always...giving everyone another reason to buy Prime.
I was also thinking that the most requested artist each month could be given the opportunity to hold a live session that would be broadcast on the Amazon Music channel. And considering the success of Ninja with the music industry, I imagine the advertising on amazon.com about the concerts could bring in even more people, and revenue to Twitch.
