If you download U2 concerts and songs is it free?

It depends on where you download them from. Many concert recordings and songs from U2 are commercially available for purchase from authorized platforms such as the iTunes Store, Google Play, or U2's official website. Downloading content without paying for it may constitute copyright infringement, which is illegal and not free.

It's always best to respect intellectual property rights and support artists by purchasing their content rather than engaging in copyright infringement.
