Well since this is resurrected now. I found a way to play your own music using a skill.
But its not very useful if you intend on playing your whole library as it involved a few steps and caveats. I would only use it now if I wanted a certain sound/song to play for a certain occsaion. One that, once set, I wouldent change it.
It pretty much involves uploading the song in a very speific format (only can be so long in length, certain size in kb, etc), then using an amazon skill to play it. The node would look like this…
