Yes, I generally write Ke$ha, P!nk, and *NSYNC. Prince goes by Prince now,
if that’s who that one symbol is supposed to be referring to. I don’t find
myself ever writing about Mike + The Mechanics (They were founded before I
was born. However, Wikipedia uses the “+” in their name.). In general, if
it’s something that can be typed on a standard keyboard, sure, why not use
it? Unlike your ABBA example (I assume it’s ABBA) that came to my inbox as A
BA, respecting their spellings doesn’t impair clarity or understanding. A
stylized logo isn’t really the same thing as capitalization anyway. It’s
not like YouTube requires Cyrillic characters.
