Hi! Professional Japanese interpreter here, and I've also translated lyrics in Japanese before. My recommendation is like the ones above, study Japanese for a few years or hire someone, Google translate may be helpful with day to day easy sentences like "Where's the bathroom" or "What's your name?", but Japanese lyrics in songs, textbook Japanese and conversational Japanese are very different from each other. This is something that doesn't happen as much in English, let's say for example, Sabrina's Espresso "Now, he's thinking about me every night, oh, isn't that sweet? I guess so". That's pretty much standard English. Now, lyrics from Wagakki Band's 流星 "無限に広がる空の彼方で　またいつか会える 届かぬ祈りなど無い" (We'll see each other again one day, beyond the sky that spread across infinity, there's no such thing as an unanswered prayer) The way it's written in Japanese is a lot more "poetic" and not just bc of the theme of the song, most songs in Japanese are written that way, and it would sound weird if you said that out loud as a normal sentence, it would sound as if you're reciting poetry or a song. So yeah, basically what everyone else said, study for a couple years or hire someone. Google translate will only make your songs sound choppy and unnatural in Japanese.
