What makes it a good cover song?

Hi guys!

What makes it a good cover? I wanted to do this post to highlight why this is a good cover without redoing the entire song in the same manner. This song basically took the catchy part from 'Can't touch this' by MC Hammer without ripping of the old hit. I honestly feel the vibe from both songs when I listen to this.

Enjoy!
