Copyright question: does this (planned) website violate song copyright?

And in this previous thread, it was pointed out to me

and a comparison to ‘Happy Birthday to You’ was made, pointing out that it’s still under copyright and can’t be sung on public performance (stage, tv, radio, etc.).

Does this site violate copyright? What are the laws?

Sounds like “fair use” to me if people are just using snippets of the total song.
