Thank you good sirs for all those kind comments (dead fish excepted).
I have been ripping classical cds at our library, on WMP set to mp3 and 256 kb/s. I use only a single level of folder, renamed for example 'Vaughan Williams - Symphony No 4'. My chromebook lists these in alphabetical sequence, resulting in a simple list of composers and works. Very straightforward, easier than trying to use a 'Music Player' app.
I can rip six cds in an hour, so it won't take too long to work my way through a hundred or two. The big bonus is that I can now listen to the work I want, rather than sitting through the other items used to fill each cd.
I am running the first few works now, and no probs so far.
