For decades, scientists have been studying the connection between eccentricity and creativity. It seems that those that more readily express their creativity in outside of the box ways have a higher distributed cognition (a different way of processing knowledge that heightens creativity). So Lady Gaga's getups and Michael's beloved chimp Bubbles are actually proof of their creativity.
For the musicians and singers amongst us that are less eccentric, this means that letting go a little may get those creative juices flowing and in turn push us to think differently and improve in ways that we wouldn’t normally.
Singing carries a message with it. If your articulation of the song's words isn't at its best or if it's drowned amongst style effects, the song's message will need to be decoded by the listener.
Unlike with a conversation, when you're singing, your listener can’t politely interrupt you with “Sorry, I didn’t catch that.” So, while you may be singing beautifully, when the message is garbled you risk frustrating and confusing your listener and ultimately diminishing the experience.
