Way back in the day, when I used to play guitar at church, I would take the hymns we were practicing and change the music. It's amazing to see how versatile some of these 300 year old lyrics really are. I'd change them up into country, jazz, and rock. One of my favourites was turning Blessed Assurance into a 90's hip hop rap. Just imagine it.
Anyway, I came across Leo who does something similar with current songs. Here's Adele's Hello. I think it's better than the original.
