The Kings of Leon frontman previously criticised the song, calling it a "piece of s**t" and branding fans of the track as "not f**king cool".
However, he insisted that he is now "ashamed" of the remarks and did not mean to offend the band's supporters.
"For a while there, I turned into someone I wasn't proud of," he told NME.
"I wasn't appreciative of the admiration we were getting, and I said some things that I'm ashamed of. I hurt people who were genuine fans of the band because I was embarrassed to look out from the stage every night and see people who weren't like me."
