How should I link to music so that anyone can open it?
I want to post about the songs that I am listening to, but in a way that everyone can open it regardless of what they are using. Is there a good way to do that? A website that generates links for the popular streaming platforms?
In some cases it can be geoblocked or would be deleted with time if IP holders demand so. But that's probably the case for most platforms. The pro-point for youtube is that it is embeddable in most social networks and website engines, so if you post it to your blog or chat it'd play within the page or app without coming to another resource.
The I permanent impermanent nature of YouTube and other host sites, such as photo bucket and forum reformats, has drastically changed how I comment. I try to type all the pertinent details instead of dropping a link alone, hoping to future-proof the info by giving readers the info required to use a search engine to find it if the link breaks
I think OP is asking for a vendor neutral application that allows the user to listen to the song on the platform of their choice, like Songlink as some suggested.
