Thanks @Kudzai Kutukwa 🙌 So, @Whisper if you just want to add random MP3 or MP4 or a link to external sources in a post, just add the link/file; if too heavy for loading files -- using NostrBuild will help (think: your storage, paid though but worth it). If on the other hand, you do music and wanna share it with others, like @Sir TJ The Wrathful mentioned already, add it to RSS feed ( with for example MSP 2.0) and compatible music player will take it can zap it etc. But it doesn't automatically post it on Nostr ( RSS = global library ; different protocol than Nostr) --- both however belong to what we call the New Music Economy / V4V music ecosystem ; lots of good stuff, profession musicians; great alternatives to all the legacy system including Spotify etc. Check for example our website https://amplifiedtunes.online/ with only a tiny part of artists that are on Nostr, and for example

Independent music from the open Podcasting 2.0 index.

to enjoy the whole library 😊 On apps like @Shosho – Live Stream on Nostr for example you can also enjoy live music and concerts. There are many other cool tools to explore but I don't wanna write here an essay 😅 Hopefully the above helps. Also consider following music related projects like for example us + @New Music Nudge Unit @2140Art+2140Music etc & selected musicians listed on our www.
