Support YouTube Music (by finding not just videos but also songs)

[lucasrangit]

When pushing a XSPF playlist is it possible to match tracks not only to YouTube videos but also to YouTube Music songs?

I believe the changes are needed in YouService.get_playlist_items(playlist). If so, I am will to try implementing this feature.

For context, I wrote a tool to export my Deezer playlists as XSPF and your tool is almost exactly what I need to import them into YouTube Music.

Check the YouService::search_track is doing the search/match per track, currently you are correct it only matches videos

@tefra ah yes, that makes much more sense! I'll take a first pass trying to match songs and let you know. Then you can decide if you want to support this and how (behind a command line argument etc...).

Thanks for the opportunity to contribute to your awesome tool!

The https://developers.google.com/youtube/v3/docs/search/list API type doesn't support songs or music (only video, channel, and/or playlist). I'm looking for another way.
