where can i download this song??

she is such a great singer, love her

yozora ni kieteku hoshi no koe
hakanage ni hikaru nibiiro no tsuki
futari de oyoida umi wa naze
tsukanoma ni iro kaete yuku n' darou

kono mama nemutte shimaitakunai...
anata wo mada kanjite'tai...

moshimo anata ga sabishii toki ni
tada soba ni iru koto sae dekinai kedo
nakusu itami wo shitta anata wa
hoka no ai wo tsukameru sou inotte iru...

itsuka anata ga yoru ni mayoi
futo ano hi wo mitsumekaesu nara
mabushisugiru taiyou no naka de
hohoemu watashi wo omotte ne

kasaneawasete yuku "suki" no tsuyosa
naku koto sae ai ni kaeta...

tsuyogaru ai no yowasa ryoute ni
kakaete moroi kizuna wo tashikameteta
demo kono toki wo ikiru anata wo
zutto zutto mimamoru my love sono kokoro ni...

nakitai toki ya kurushii toki wa
watashi wo omoidashite kurereba ii
yorisoeru basho tooi natsu no hi
nukumori ikiru yorokobi
subete no kokoro ni...
