Stargazing: Sparkle - Arisaka Mika
How about we step away from the anime specific songs for a day, and even jump away from the Japanese language altogether?
Yes, it's still performed by a Japanese artist, Arisaka Mika. This funky tune is entirely written with English lyrics, and it's clear she knows her pronunciations well. It's really hard not to sing along to this one, since it's so easy to learn the lyrics.
