I'll be honest with you, I did inspire myself on the way the singer from Kings of Leon sings on The Bucket, but it was just a source of inspiration nothing more. No, I'm not a J. Casablanca wannabe, I just couldn't sing higher than this or I'd be screaming on parts of the song. As for the similarity to The Strokes you're not the first to mention that, but that came to me after composing the song... it came out naturally. Moreover, this was initially in a bossanova rythm, very slow and then evolved into a faster style.
I really don't see this as any plagiarism, not anymore than Jet are from The Beatles, or The Strokes are from Velvet Underground. There will always be connections and similarities between songs and music styles.
It would be wrong from me to change parts of the song, so they won't sound like some other band. If it came out this way naturally, then in my opinion that's how it should stay.
