Some very nasty static around here. Ignoring it is the best way. ............................................
"Twee" is one of those value loaded words which distort discussions. By that I mean, instead of discussing the merits and demerits of singers, we get sidetracked into discussing the meanings of words.
If we say a singer's style,is highly emotional, or or free from emotion, or simple, or complicated, or natural or artificial, we can agree about that, and move the argument on to whether we think that these qualities detract from the performance or not.
But a word like "twee" leaves as stuck at the starting line - because agreeing to us that word to describe the performance means that we have dismissed it as essentially worthless.
