I recall that Beyoncé has several hits like "Single Ladies," "Halo," "Love on Top," but nothing called "POISON." Maybe the user is confused. Could it be a song from another artist with a similar title? For example, there's a British band called Poison Ivy, but that's a band. Alternatively, maybe they heard the song in a movie or a show.

Another angle: sometimes people use "POISON" as a nickname for a song. For example, if someone really dislikes a song, they might call it "the poison song." But that's a stretch. More likely, they just got the title wrong.

Is there a new Beyoncé track that was recently released? I should verify that. As of the latest info, her most recent album is "Cowboy Carter" in 2024, so maybe it's a track from there. Checking the tracklist: titles like "Texas Hold 'Em," "Jealousy, Jealousy," but no "POISON." Hmm.

I should also consider that the user might be looking for a fan-made track or an independent artist's cover. In that case, they should look for legal avenues. Emphasizing legal downloads is important to avoid copyright issues. Suggesting platforms like Apple Music, Spotify, Amazon Music, or the official Beyoncé store would be helpful.

Also, considering that Beyoncé sometimes releases visual albums or live performances that might have unique titles. The user might have heard a snippet and got the title wrong. Could it be a song from her "Lemonade" album? There's "Love Drought" or "Sandcastles," but not POISON.

Another angle: sometimes people refer to songs by the wrong name, especially if translated phonetically. "POISON" might be a mistranslation. Let me think of any Beyoncé songs that could be misheard as "POISON." Maybe "Halo" sounds similar to some, or "Ring the Alarm"? Not quite.
