One Direction 'Best Song Ever' Leaked, Niall Horan 'Frustrated' [LISTEN]: Doesn't Want Fans to Hear 'Dodgy Internet Version,' Radio Debut Today, Twitter Reacts

One Direction's highly anticipated new single "Best Song Ever," which was teased in a trailer for their even more anticipated documentary concert film This is Us, was leaked earlier this week. Most of the links have been taken down, but the boys were still affected by the leak, including Irish heartthrob Niall Horan. The singer was recently on Australian radio show Nova FM where he was asked about the leak, revealing his true feelings that are probably shared by band mates Harry Styles, Louis Tomlinson, Liam Payne and Zayn Malik.

"Because it was leaked today, obviously it's a little bit frustrating cause we were wanting the fans to hear it," Niall said.

Horan's concern for his fans was adamant in his "frustation" statement as he said he didn't want the fans to experience this new song for the first time as a "dodgy internet version."

You can probably bet that most fans jumped on the leaked audio, though. Sorry, Niall!

Niall's band mate Harry Styles took to BBC Radio 1 today for the song's official radio premiere.

"'Best Song Ever' is my favorite song we've done so far..." he admitted to radio host Scott Mills. "It's just a little bit heavier, not like Slipknot or anything but the chords are bigger, the drums are bigger, the guitars are bigger. So, we really like it."
