The question seems ambiguous. I think the answer would be different for any two songs that you want to compare. If you're looking for a general answer, I think that if you compared typical songs written in the 1940's with typical songs written now, here are the typical differences:
1. Old songs have lyrics that were carefully crafted, and the arrangements showcase the lyrics.
2. New songs emphasize arrangements and the emotionalism of the singer. The lyrics may not even be intelligible.
3. Songs used to be written by songwriters for singers.
4. Songs now are written by bands for bands.
I'm generalizing, but the question seems to ask for it.
There are no similarities only differences.
Old music is for old people who are going to die soon so they like boring music cause they are boring.
New music is for young people who are healthy and cool. New music is more original and unusual. Old people just can't understand it cause they got used to their old boring stuff and can't understand nothing new.
