Great post, Dave.
There are quite a few sites where you can hear some of the more popular music of the day. Here are one or two on parlour music, and you can download the sheet music if you have Scorch or Sibelius, and you feel like trilling away in harmony. When I was a child, my father used to play (piano - badly) some of the songs his mother played to him. The sentimentality Dave referred to is quite extraordinary, but often very social in origin, involving drunken fathers in the pub, dying children, abandoned fallen women etc. My father used to reduce me to tears as a small girl, singing
The Miner's Dying Child. Impoverished, over-worked and harassed miner's wife, mother of many, watches over her dying youngest. Infant's last words are,
"When I get to Heaven, mother, will I be in the way?"
Cue torrents. Mind you, I was always being told I was in the way myself. My father, the s~~~~~, just used to laugh at me, and launch into
Home Sweet Home, telling me that it was written by a starving and freezing tramp dying of TB. I'm absolutely sure it certainly was not, but I believed it at the time.
LINKS TO LYRICS SITES

The last one links to all sorts of music sites with midi files, and a very good one there for listening to piano music of the time is
Perfessor Bill Edwards - he is extraordinarily generous in putting his great early song and ragtime playing on the Web for free (piano not midi).
The next is a site for hearing Gilbert & Sullivan music - it's only midi of course, and has no singing, but you can get an idea of the tunefulness of it and how people would have wanted to sing it in their own homes. Lyrics are available - and they are always rather good in G & S. Some great political / establishment satire.
Home page for MIDI files of songs from the operas in the Gilbert and Sullivan Archive, as well as much other music by Sir Arthur Sullivan and other light opera composers.

One of the most famous miner's bands in the UK is the Grimethorpe Colliery Band, who always seem to win everything, and - although the mine closed in 1992 - still have ex-miners as the majority of the band I think.
Also popular in the US at the time was barbershop singing, and here is a site where you can listen to "The Light of the Silvery Moon" as originally recorded at the beginning of the 20th Century, amongst other things.
Don't know so much about early 20th century taste in classical music. Always assumed their taste would be late 18th / 19th century - rather like mine. And I don't like Vivaldi either.... and speaking of atonal music, I once endured 3 hours of Hoddinot. The scars ...!
