Ian,

I scrolled through the tread and there is IMO a sane and pragmatic approach to mobile. Personally, this is not about improving Google's view of your website; more about making the visitors experience more enjoyable.

I modified my audio player template to allow songs to be easily selected by alphanumeric song groups (the same as your current site); your pages for intro, ref and updates would be easy to transition to a mobile portrait format and you could use your own buttons too. I would though suggest the start point is a structure that lends itself to mobile and one that could be easily maintained. My start point would be to create an entirely separate development URL (e.g. https://mydomain/test) - relatively easy thereafter to expand the test site to have a desktop variant that transitions from portrait to landscape. You only make a switch when everything is working.

There is a little bit of code in the Website HTML body, but I've stripped out the extras to keep it simple. I have assumed you have all your songs in a server-side directory; if true this template would work well - more labour intensive that technical. The links to the songs are easy in that you just change the source in the HTML code and insert your song titles in the links, page-by-page. Where the song has additional information, the structure allows one to place all this on a corresponding popup. This includes videos (which would benefit from some additional code) to ensure a video opens and closes correctly on a popup, per the Jukebox v5 code: https://initiostar.co.uk/demo/JukeBoxv5/ - Fairly straight-forward to add if and when required.

Here is a demo: Jukebox-v6-mobile.xar - not fully tested as yet, but it would give you an idea. I have left the jQuery tag on the index page, though the striped-down version does not require it. There is probably a better way to manage the alphanumeric grid too, but I've not ventured that far.

When you have time take a look - it takes about 4 mins to add and test a song, but best use Notepad++ or similar to create the list of links.

Maybe some help for the future.
