Hunting down the lyrics to 'Sunshine Rainbow White Pony' was kind of a mini-quest for me last week, and I ended up piecing them together from a few legit places.
First stop: the artist's official channels. I checked the musician's website and their official YouTube upload; a lot of artists put full lyrics in the video description or on a lyrics page. If that doesn't pan out, I usually try streaming services—Spotify and Apple Music both show licensed, time-synced lyrics now, and that helped me confirm lines when different websites disagreed.
When those three fail, Musixmatch and Genius are my fallback. Musixmatch often syncs with players and shows the exact lines; Genius gives annotations that sometimes explain odd phrases or references. I avoid shady lyric-scraper sites because they tend to be wrong and could be missing verses. For completeness I sometimes check Reddit threads or fan communities for verified transcriptions and translations. In the end I cross-reference two or three sources to feel confident, and honestly I love spotting little misheard-lyric moments along the way.
