The main theme of the anime Bishoujo Senshi Sailor Moon ( 美少女戦士セーラームーン ). It is a legendary masterpiece and literally tells the legend the anime is based on, and thus the title itself means Moonlight Legend. One of my favorite songs ever. :)

Lyrics:

Gomen ne sunao janakute
Yume no naka nara ieru
Shikou kairo wa shooto sunzen
Ima sugu aitai yo
Nakitaku naru you na moonlight
Denwa mo dekinai midnight
Datte junjou doushiyou
Haato wa mangekyou

Tsuki no hikari ni michibikare
Nando mo meguriau
Seiza no matataki kazoe uranau koi no yukue
Onaji kuni ni umareta no mirakuru romansu

Moichido futari de weekend
Kamisama kanaete happy-end
Genzai kako mirai mo
Anata ni kubittake

Deatta toki no natsukashii
Manazashi wasurenai
Ikusenman no hoshi kara anata wo mitsukerareru
Guuzen mo chansu ni kaeru ikikata ga suki yo

Fushigi na kiseki kurosu shite
Nando mo meguri au
Seiza no matataki kazoe uranau koi no yukue
Onaji kuni ni umareta no mirakuru romansu
Shinjite iru no mirakuru romansu
