I love Cher, though I still love Madonna far more than her. Her music to me is still pretty good, and I think she has had areas of making worse music than she currently is now. For example, I don't really like the music from True Blue to Causing A Commotion, but then she went and did Like A Prayer and was better than she had been beforehand.
I don't think her music currently is as bad as it was then, and I do hope she can lift herself again, just for at least one more great album. But I like her being around as only she, U2, George Michael, Bon Jovi and Kylie Minogue have been charting consistently since the 80s off the top of my head and I hope they can all last as long as possible because I still enjoy their stuff (except Michael and Bon Jovi are starting to drag).
So, in closing, praise Madonna. She is the biggest selling star internationally of the 80s, and it's not like the music scene is that great right now.
