Soulful
Though the quality be a low and the sound be muffled, this remains a beautiful song. I can feel the pain, the bittersweet memories, and the sheer emotion poured into this one.
The chords were beautiful, the melody was expressive, and I love it. Do yourself a favor, though, and go buy some nice software and a good mic. Your music deserves no less.
You grandfather would be proud. :)
