English in Japanese Songs

[ohsixthirty]

hey, i remember you! especially for your avatar!

but yeah, i agree with what others have said, i think its used for the "cool" factor. and also i think that it places emphasis on certain words if they're sung in english, it makes them stand out more. its the same concept as japanese people wearing shirts with english phrases on them...even though the english may not make perfect sense, aesthetically its pleasing.
