Yeah, as zeldaskitten et al said, there are a lot of songs where particle wo sounds like wo instead of o. Songs often make all sorts of dropped vowels quite distinct. Music isn’t a great place to pick up pronunciation. Words with “shite” usually have an almost silent i, and words like ikitai usually have an almost silent i in ki. Music brings those i sounds forward much of the time.
Sorry for all the romaji. I ‘m stuck with devices on which I can’t type kana today. They support reading, though, so it doesn’t bother me much.
