That my favorite greek singer, demis roussos died in 2015

and if he was alive today he'd be 74

this makes me sad. He has such a lovely voice and he will never release any new music

the person who told me said that it's okay, because he did a good job and he left behind a good legacy, but still I am upset by it

Of course you're still upset by it, that makes sense to me. I mean, you just found out about it, so it hasn't had time to sink in. Leaving a good legacy is wonderful, but it doesn't make someone less dead, so of course you feel sad and upset.

thank you for your reply. I really do apreciate it

Understandable, Michael Jackson died and i feel the same way. Just be strong and try and prolong your life as much as possible, although even this isnt a guarantee.
