Hello ekitcho,

There is 2 more things I wanted to suggest for busy :) I'm really excited by the potential of this site because you guys have the vision and are thinking big, which tells me this thing is gonna be yuuuge !
Anyway here are my suggestions.

You could use @radiosteem or something similar to allow people to pay to get their song heard by all the busy users. This is something people have always liked, when they think a song is good they want the world to hear it, people could even burn some steem just to get their song heard live by everyone, you could add a steem music player on the interface or something.

The second suggestion is to create a free daily lottery. So that busy can make someone's day everyday, this is very good for user retention, the hope that you can win the busy lottery one day will keep people coming back everyday and also because its free.
It is pretty simple to do basically you need to allocate a unique number to each user using busy. Then these users can just cast their vote for the lottery on the interface so everyday the amount will be different. And finally you need to make the rules clear , basically you can use first or last random hash numbers of a certain block and when this number correspond to the user's unique number he wins. It sounds a bit complexe but It really isn't.
here are some lottery project based on the blockchain https://github.com/ghgr/LottoMotto-Bitcoin https://github.com/EarthLottery/EarthLottery https://github.com/hmel/bitcoin-raffle

A free daily lottery will have everyone coming back , no users will leave for good :)

Let me know what you think
