Surely someone must have made a thread nearly identical to this in the past? Nevertheless, the most beautiful melody you've ever heard is worth repeating! I understand it might be hard to narrow it down. Mention two or three if you must.
Every musical thread seems to be people responding with "Classical Song X" and here I am with "90s Rock Song".
Anyway, I have love for a lot of great melodies, but the one that popped into my head when I first saw this topic is the intro guitar riff of Seven Mary Three's "Waters Edge". I was on a speech competition trip in high school when we stopped at a fast food joint on the way home and I heard this come on the radio. I was instantly in love with it and although I wasn't sure if the rest of the song sucked or not, I HAD to know what the song was. Fortunately there were 2 metal enthusiasts in line behind me and they were able to tell me the song and who performed it. This was before I owned a cell phone so I repeated the name Seven Mary Three over and over in my head the rest of the way home.
