You're welcome! Apparently, there's also an "order" in which each of them sing their solos. Usually Liam will start the song, followed by Harry singing the bridge, then Zayn, Niall and lastly, Louis. Most of the songs will be in this "order", however there are some exceptions such as
I Want and
Little Things. I think there could be a few more, but didn't really pay too much attention to it. Gawd, this is what happens when you keep listening to 1D on repeat mode.
As much as I
adore Louis and all of his sassy glory, I have to admit that he's the weakest singer among the five of them, but I would not go as far as to critique him, because the lad can sing. Just that his vocal's ain't strong unlike Liam or Harry's. But his voice does have some kind of charm which makes me go, "Awwww..."
