Well, those were simpler days.
When MTV got away from the music and started with that left-leaning "original" programming, it was all downhill from there.
On YouTube, they have a VEVO channel where you can see most of those videos.
By the way, that VEVO channel is making the music industry billions of dollars. What used to be given away as promotional videos is now a cash cow. Everytime somebody queues up a Cyndi Lauper video on YouTube, she gets a nickel. It adds up quicker than you think.
It’s not nearly a nickel per viewer on Youtube, maybe per thousand views
You can also watch full concerts on youtube, Vevo and others.
