Not impressed at all with Roar. It's kinda different from TD material, but still not very far from it.
No defined melody per se, no pre-chorus. Decent verses, but somehow monotone. Pretty much no middle 8/bridge. All into chorus type of song, but the chorus itself is not THAT great either.
+ those basic oh-oh-oh's after the chorus which makes it sound cheap.
Feel-good type of party song 3/5
Lol this is pretty much what everyone said when Diamonds premiered, word for word. And we know how that went.
