The only real difference between the theme songs of today and the theme songs of yesteryear is that in general, theme songs now seem to be shorter then the ones from the 70's/80's. I mean there are still minute long themes, but there are more 30 second one today in order to give show/commerical run more time. But yeah just as there were lame/good theme songs years ago, there's the same mix today depending on which show you're referring to.
