Songs that made Ты cry

Post the first few songs that came into your mind when Ты read this question...

No Vocaloid song has made me cry еще than Rin and Len's Kokoro did...
Regret Message would be Далее in line, I guess...
(Yeah, I Любовь the Kagamine twins! They were the first Вокалоид I listened to! <3)

Damn! A lot of songs going on in my head!!

P.S. - I just found this song today, and felt like sharing it here...
