Antiwarsongs.org is a niche archive dedicated to protest songs, and it has the look of a long-running passion project. The available signals show no security warnings or blacklist activity, and nothing about the domain setup suggests this is a makeshift scam site. For an independent music resource, that's a solid starting point.
The biggest limit is the lack of a visible owner. There's no clear contact page or social media trail, so if you need to ask permission to reuse lyrics or recordings, you may not get an answer. That's common for vintage hobby sites, but it does mean you're relying on the archive as-is.
If you're asking whether antiwarsongs.org is a scam, the simple answer is that nothing in the evidence points that way. Treat it as a reference library, not a store. Enjoy the songs and historical notes, and be wary of any unexpected download prompts. A site that has persisted this long while staying off watchlists deserves a neutral-to-positive read.
