I still sing Obladi-Oblada in my set, [I'm a guitar/vocalist doing local pubs and clubs in UK].
The audiences still sing along and dance to it and many others, I do some just to annoy people like;
The Birdies Dance [yeh honest]
Chirpy Chirpy Cheep Cheep
Doo Wah Diddy
and there's more...
But I try to even up the dumb/intelligent balance by playing;
Something Inside So Strong
Drift Away
I Saw Her Standing There ... a cracking Macca song, I'm sure you'll agree
Wonderful Tonight
etc etc
I wont even go into the lower forms of music like; rap punk or Oasis [lol]
In all honesty, modern music, maybe goes more into the less innocent themes, [not the I love you, you love me..forever and ever stuff of the 50's and 60's], it's more brutal these days, and maybe that's sad in itself, as maybe pop music is committing suicide.
Music for the masses, it may be, but styles and fashions are created and directed by the suits and producers, whose only interest is making another million on the backs of the young and gullible.
Check out Simon Cowell; eats `em up and spits `em out. In other words, he makes and act, [usually mildly talented] makes them into household names, then before they can ask to actually have a say in their next recording he drops them for another flash in the pan!
Sorry...another sermon, I'd better log off
if your a wannabe...keep trying and ignore the above
