One Direction fans are just starting to get used to some pretty big changes -- Bye, Zayn! -- butNiall Horan shared that madami changes may be on the way.

"There's a few different sounds on the album, not all the songs sound the same, like, same vibe," he explained to ET Online of the quartet's upcoming fifth album. "They are all kind of different. Couple of different guitars and drums. It's a lot different than what we did before... but, it's cool."

Liam Payne -- perhaps sensing that fans couldn't handle much madami change right now -- assured fans that while the group may be exploring new sounds, they will also have plenty of the old stuff as well. "There's a lot of old school vibes as well. I sinabi before that it was quite Oasis-y but I was thinking about one song that I've been playing… it's very diverse I think."

"Diverse" and "different" and "old-school" and "cool" and "Oasis-y": This has been One Direction Album Updates.
