You are totally right. The benefit to the consumer needs to be a closer relationship with the artist where they can also be rewarded when they join in the discussion.
The blockchain equivalent to Spotify (note @Steemsongs is more like the iTunes store) will offer faster and larger payments to artists, as well as faster and larger payments to record labels. The record labels being paid more is key to an equivalent service taking off.
The key to @steemsongs success will be in offering something different, ideally I'd like to make it much more curated. Also Steemsongs will allow Steemit users (500k currently) somewhere to spend their Steem/SBD as oppose to cashing out immediately. One gripe I have with Steemit is the complete lack of monetisation. Why can't we pay SBD/Steem to upgrade our accounts, to unlock private messaging... and why aren't Steemit INC using their stake for good instead of delegating to repeat posters?
The project remains a way for me to combine two things that I love: music and blockchain. I don't know where it will go, but hopefully you'll come along for the ride.
