It's funny you mentioned a favorite artist maybe not being plentiful...

I think in a decade there will be an app that let's you choose the parameters of the music you want to hear and it will spit out something by whoever you want featuring anyone else, whether they would approve or not, and no one will know the difference except us old fucks who used to have to wait for a band to record something like a bunch of savages.

Can't wait to hear that Andy Griffith/GWAR harmonizing to the background of a John Wayne and Michael Jackson rap battle.

Edit to add this one...

I was into Nirvana as a teen and this could almost be straight out of Cobain's notepad.
