Second reason, it's because of the guy's voice. His voice doesn't make feel sad. It makes me feel pain. It makes me feel his pain, and reminds me of my pain.
The last reason would be because the song's played with just two guitars through out the whole song, and it doesn't sound over-produced like the mainstream ballads you hear on MTV. This song sounds honest, in a way.
Anyways, go check this song out.
Nadia's Picture Show - Menunggu Dirimu
Semuanya kan berakhir
Kiranya kau kan mungkir
Tetapku menunggu mu
Untuk kau terus berfikir
Jangan kau anggap ini semuanya
Hanya mimpi yang tak berharga
Jangan kau hampa tentang isinya
Kenangan yang telah kita bina
Hanyaku yang inginkan semua
Untuk kita terus berdua
Ku kan terus tersiksa
Kiranya aku tetapkan menunggu dirimu
Harusku menahan semua kisah cintaku
Jauh, jauh….
Jauh…
p/s: this song will forever remind me of that emo girl
