I'm all about the VOICE and how it's used to give you that special exciting feeling when you listen to music. I've been thinking about this a lot lately, and it's something that's hard to come up with an ultimate conclusion for, but I think my choice for the best vocals, not just for my fave artist (MJ obvs), but just ever, would be shoo-bee-doo-da-day. When I first came across it, the name sounded odd, but after listening to it for a while, while on my commute to university, I just couldn't shake the thought of how amazing the vocals on it are. I looked the song up and found out it was originally by Stevie Wonder. Listened to his version. It was too slow and the vocals couldn't be compared between the two. Shit starts getting crazy around 1:34 and it doesn't stop.
TL;DR what the title says.
