Of course Disney is going to have their stable of artists cover their classics!
Cruella De Vil was one of the nastiest Disney villains - I mean, who the hell is going to make a coat out of dogs?! She was so iconic, she got her own song. On a personal note, it's one of my favorite Disney songs, even in its original version. I remember seeing 101 Dalmations at the drive-in - yes, I'm that old - and it made quite an impression.
This version, however, adds to the original - it brings a lot more guitar and energy, yet stays somewhat creepy. Selena's raspy voice is well-suited for the tune. Also, if you think Selena Gomez is a (Wicked) Guilty Pleasure, you're right.
