Okay, but I don't think Miley Cyrus has anything to offer other than funtime nonsense. Here are the
writing credits for the songs on an album called Bangerz. An album title with the urban z, and songs written by committee. Whereas the Dolls, as you rightly point out, came out of the gutter, did things on their own, and offered far more than just fun.
It's very possible that despite their apparent differences and the vapidity of her output, Morrissey and Miley Cyrus genuinely enjoy each other's company and are friends. I'll file it under curveball.
