I love Daft Punk, I love the Gorillaz, and Queen is amazing, but when I have to think of the most beautiful song my ears have experienced so far in my life, One More Time, One More Chance by Masayoshi Yamazaki was one of the first to my head. It's one of the most famous songs in Japan, and it has earned it's fame.

Even if you don't know Japanese, you can feel the beauty of the song(besides, not only is music universal, the video has English translations on the fly!). The artist lost his girlfriend in an earthquake a few years prior to writing this song, and his pain from his lost love shows in this song, both lyrically and emotionally. Even in the music video, he looks and sounds like he's ready to burst into tears at any moment mid-performance. If you don't feel anything after hearing this song, even after getting to know the lyrics, you're simply not a living being.
