Time for a sing along! XD. The background song is Melissa from FMA! One of my favorites, second to UNDO! Anyway, the artist who sings this song is porno grafitti lol. XD Anyway, here're the lyrics! Its japanese so just try and keep up with the beat ^^.  

Kimi no te de kirisaite Tooi hi no kioku wo
Kanashimi no iki no ne wo tometekure yo
Saa Ai ni kogareta mune wo tsuranuke

Asu ga kuru hazu no sora wo mite Mayou bakari no kokoro moteamashiteru
Katawara no tori ga habataita Doko ka hikari wo mitsukerareta no ka na
 
Na a Omae no se ni ore mo nosetekurenai ka?
Soshite ichiban takai toko de okizari ni shite yasashisa kara toozakete
 
Kimi no te de kirisaite Tooi hi no kioku wo
Kanashimi no iki no ne wo tometekure yo
Saa Ai ni kogareta mune wo tsuranuke
 
Tori wo yuuyami ni miokutta Chi wo hau bakari no ore wo kaze ga nazeru
Hane ga hoshii to wa iwanai sa Semete chuu ni mau MELISSA no ha ni naritai
 
Mou Zuibun to tachitsukushite mita kedo
Tabun kotae wa nai no darou Kono kaze ni mo iku ate nado nai you ni
 
Kimi no te de kagi wo kakete Tamerai nado nai daro
Machigatte mo Nidoto aku koto no nai you ni
Saa Jou no ochiru oto de owarasete
 
Sukui no nai tamashii wa nagasarete kieyuku
Kieteyuku shunkan ni wazuka hikaru
Ima Tsuki ga michiru yoru wo umidasu no sa
