All you need is a website and an RSS feed, which is an XML file! nostr:nprofile1qqszxgvrzkpasudhvdjx3anl77qxse5wd6eunndmyv9x63uwnpn09mgpr4mhxue69uhkummnw3ezucnfw33k76twv4ezuum0vd5kzmp0qyghwumn8ghj7mn0wd68ytnhd9hx2tcpzfmhxue69uhkummnw3e82efwvdhk6tcgt4a3x can help you get started. Then you submit your feed to the Podcast Index and EVERY Podcasting 2.0 player picks it up.
And once you're comfortable DIYing the RSS feed, you can teach musicians to do the same! There's a handy copy-and-paste RSS feed for decentralized music (DeMu) already:
