Hi Henrik, thanks a lot for your kind words!
1) Yes, EPs and Albums can be published as well. See example https://sunami.app/release/naddr1qvzqqqy9tvpzq0c34wewydw694xa5htdavh3yvtnga48gk3u545ftgws7ce2gt6qqyt8wumn8ghj7un9d3shjtnswf5k6ctv9ehx2aqpz3mhxue69uhhyetvv9ujuerpd46hxtnfduqs6amnwvaz7tmwdaejumr0dsq32amnwvaz7tmjv4kxz7fwv35hgar09ec82csqz4jxzuntwajkytf3xumr2wpsxqunvwpkxuusp253rh
2) We support WAV, FLAC, OGG, MP3, M4A and don't really convert music files. By default music is uploaded to Blossom (Nostr Content) service and you can configure custom servers if you have preference. At the same time you can just reference link to your file of it's hosted somewhere.
3) You can upload via Sunami purely to Nostr Music. So no duplicating of confuing RSS feeds by default. If you want you can enable RSS on demand and submit to Podcastindex which will make it appear everywhere.
Let us know if it can be done in a more user friendly way.
