Good thing your getting clues where to find what you want..
When I first read your post I thought " Thats a tough project since the new electronics for our 'children'
advertise a selection of 60,000 ( sixty thousand ) songs."
I just got the new issue of NatGeo, on the back page is an advert for the new Kindle educational book......
Features 17,000,000 ( seventeen million ) songs.
Is there still anyone alive that remembers what they used to call "the top forty"
