^ I believe that both of those Kiss songs were also wrote in/for the tragic death of another great musician in the band. So many wonderful musicians have died so young either by their own faults (such as drugs, alcohol, sex, suicide, etc...) or simply by being murdered or passing in other unfortunate ways. As far as emotional songs and/or titles go, the song "Gone Too Soon" by Michael Jackson flat out plants the message into everyone's head. Here's a list of a few musicians that come to mind for leaving us all too soon...
1. Kurt Cobain.
2. John Lennon.
3. Michael Jackson.
4. Stevie Ray Vaughan.
5. Randy Rhoads.
6. Michael Hutchence.
7. Eric Carr.
8. Cliff Burton.
9. Darrell Abbott.
10. Whitney Houston.
There's surely a ton more, but those come to mind first & are all so devasting & impactful to the music world.
