How i can get romanji/romanja from Korean/Japanese Lyric?

[#1]

You know that so many people around the world singing and listening on Spotify. But, the people don't have same language. Because of that, the people like me want to read the lyric like Japanese/Korean/China song, so that I can sing the song. Please input the Romanji/Romanja Theme on the lyric. I know that the third app of Spotify has the theme/feature, but I'm afraid downloading it is illegal. May I download it? I never use the adblocker, because I have the Premium Student. Or, What is your solution from this problem?
