Taylor Swift's Writing Pal Ryan Tedder Spills Deets On Her New Album

"I did a little stuff with Taylor, who’s probably the fastest songwriter I ever met in my life. I can go on record saying that Taylor is genuinely the quickest songwriter I’ve ever- for anyone who doubts it she writes her own stuff. Any idea and you’re like “Yeah I don’t know if I like that lyric” and she’ll have three options, replaced within 10 seconds, she’s like bam bam bam. She’s bit of a prodigy, bit of a songwriting prodigy."
