I guess it depends on how you go about it? I don't know Chris Cornell and I know Prince but am pretty ambivalent on Prince, but I adored Bowie. I wasn't garment rending, loud wailing, teeth gnashing sad when he passed, though I was sad because his music was part of my formative years and as a person he always seemed so confident and himself, which helped me do the same.

For people who had a lot more things personally going on in their lives where music means more to them than just something to listen to, I can see being despaired by that musician's death if it was something that helped them cope.

I however do find myself finding the public displays of over-dramatic written sobbing etc to be a little ridiculous. Not the heartfelt posts of 'so and so meant so much to me and got me through hard times' though.
