I plan on using Emubands they get on Spotify which was my main concern. As well as most major music platforms I believe like Google store and itunes. They charge a one-time fee and take no royalties, I didn't want to have to pay every year to keep my music on platforms. They've got pricing for singles, eps 3-5 and albums 6-20ish I think. Starts around 45$ for single
I've used State51 for a few years, decent guys to work with.
I don't write for aggregator companies anymore, prefer to mix and produce these days, but this is their current distribution list.
