out contract for digital distribution with ReverbNation says they will deliver to spotify!
Why can't I find CHICA TORPEDO on Spotify... and if I find tracks, why the buy-button is not enabled?
The content is probably in an upload queue. Usually it takes about 4-6 weeks for content to get your music on Spotify. To be on the safe side, you could check with ReverbNation for a timeline.
Could send a screen shot regarding the issue with the buy button?
