My concerns are 'mostly' just related to music, but sure, I see (usually young) newsreaders on TV using exaggerated emphasis to sound like they are really INTO the story...sometimes with EVERY other WORD punched to be SURE the listener KNOWS how CONCERNED they are. *grin*
(One example of this is the BBC 'reporter' Richard Quest, (now on CNN International), who drives me right up the wall with his posturing and stuffy delivery....with facial grimaces added)

but about music....

Occasionally at festival workshops, there will be some sort of exercise loosely titled "Making a song your own"....now I know roughly what that is intended to convey, but I fear that some distort the idea badly.

Of COURSE we don't all do a song exactly the same, and there is always room for interpretation of tone and mood..etc....but when meter, volume, tune....and even major lyrics segments are gratuitously altered primarily to showcase the **performer** and his/her (often debatable) talents, the song usually suffers.

If a skilled performer does a song well, so that the content is appreciated, the performer will be admired and remembered....if the presentation is awkward, the tune distorted, and the lyrics 'messed with' excessively, I question whether they care much as long as they are getting attention.

(I could have found a simpler way to say all that.....maybe I need to take my own advice)
