fsdhjkl not me just now realizing that "Happily" (aka one of the best songs on MM) is written/produced by Savan Kotecha and Carl Falk who are part of the team that brought us WMYB/LWWY/every other song by 1D that sounds like those singles.
Note that Rami Yacoub is nowhere to be found on this track. Which is interesting because the song is still immediately catchy yet doesn't sound like a copy of their previous uptempo singles. Does this mean Yacoub is to blame for the similar melodies, guitar riffs, etc on their other tracks with 1D?
Rami Yacoub, the Swedish Dr. Luke
That's usually how it is with boybands isn't it? In NSYNC JT and JC only had solos for the most part. I never really checked for BSB so I wouldn't know. I only know of Nick Carter.
