I think jazzists will be very bothered by this take. jazz is for ordinary people by berlioz is a lovely introduction. Its pop-ey and dancey and quiet nice.
if you want something a little softer and a little more classic:
Chet Baker Sings is a sweet place to start.
The songs used in kids on the slope has like a lot of the trad "must listen" songs that are both great and still pretty pop forward. it showcases the early genre well.
