there's a difference between an artist's style and repetition
to me, it doesn't matter if an artist uses the same of an element of a song in most, if not all of their tracks, as long as they either do new, creative things with it, or they flourish the rest of the song to the point where the repeated song element is balanced by what the artist has done with the rest of the song.
plus, i'm pretty sure rogue uses similar elements of bass in a lot of his songs - i noticed a lot of similarities with the sounds in the drops of "Tigers" and "Adventure Time"
