Same here. I've generally found complaints about Google's recent decline to be overblown, but lyrics are one area where it's truly gone off the deep end.
Even if I type in 2-3 lines worth of nearly-exact lyrics that show up on multiple lyrics websites, it'll give me completely unrelated songs that match several words at most.
On that note, if anyone needs a good browser-based song finder, the "Aha Music Identifier" extension is pretty good. It's a life saver when watching Twitch streams that don't list the currently-playing song.
