Searching for a song by typing in lyrics is specifically a feature I’ve noticed Google can’t do any more. And it used to be able to.
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.
On the other hand, chatgpt 4o-mini and 3.5 will just make up source material which is amusing but not very helpful.
