OneRepublic frontman and songwriter Ryan Tedder called into radio station KIIS, revealing that he is working with a band in top secret fashion -- but it's not Imagine Dragons! He also shared a key feature that songbirds Ariana Grande and Taylor Swift have in common when it comes to creating music. 

According to Tedder, both Grande and T. Swizzle are fast when it comes to their craft. They do not waste any time, likely because they don't have many minutes to squander, given their busy lives and careers. Plus, when you are as good at what you do as these two are, things come quickly.

"I was in with Ariana a few days ago," the singer and songwriter said. "She is one of the fastest singers I've EVER heard in my life and is just amazing. We knocked out two songs in a day. I did a little stuff with Taylor [Swift], who is probably the fastest songwriter I've ever met in my life."

Tedder joked that he sometimes gets in trouble for making reveals about his work in the media, but he confirmed that he could go on record about T. Swizz.

He furthered, "Taylor is genuinely the quickest songwriter. For anyone who doubts it, she writes her own stuff…. Any idea, you're like, 'Yeah, I don't know if I like that lyric,' she has three options to replace it within 10 seconds. She is like bam bam bam. She's a bit of a prodigy, a bit of a songwriting prodigy."

Yeah, we pretty much knew that already!
