Ed Sheeran
is one talented guy ... we can see why Taylor Swift's a fan!

The red-headed singer stripped down and mashed up Blackstreet's "No Diggity" and Macklemore's "Thrift Shop" with the help of Passenger for the Australian radio show "Fifi & Jules," on Wednesday -- and it sounds a-m-a-z-i-n-g!

Who knew that the R&B tunes would sound so incredible acoustic?

If you haven't heard of the British singer, he also writes songs for One Direction (and he's good friends Harry Styles) ... and he's been linked to Taylor Swift!

Check out his awesome "No Diggity" mash up above and just for fun, take a listen to his version of Rihanna's "We Found Love" below. What do you think of his covers? Sound off below!
