THIS IS IT.
Ok, I guess Era should have come to mind, but if I'm not mistaken I've looked at their songs and did not find it.
EDIT: I'm not finding this in the Era discography.
EDIT 2: I'm totally confused who is author here.
EDIT3: Ok, I'm not senile. It is not Era. It is something called "Ocean Voyager - Titanic Expedition".
Here is an actual clip with the real name
The first two comments: "You have no idea for how long i was looking this song." and "finally i've found this song :)Thanks"
Something about this makes is very hard to find.
