There is no such thing as an “international copyright” that
will automatically protect an author’s writings throughout
the world. Protection against unauthorized use in a particular
country depends on the national laws of that country.

Having said that Iceland has an agreement with the United States.

Iceland · Berne (Paris) Sept. 7, 1947; UCC
Geneva Dec. 18, 1956; WTO Jan. 1, 1995

However unlikely it is that you will suffer any negative consequences for Copywrite infringement, it is certainly possible. The penalties can be quite severe and are occasionally enforced.

Website owners also have some legal liability for illegal content posted on their site although laws concerning these issues are often contested.

You can however easily obtain permission to do a cover song. It is not free but only cost around $15.00 US in most cases.

Many of us, both owners of copywrites, and users of copyrighted material are not happy with the current laws but they are on the books and need to be complied with however frustrating they may be.

I am not trying to tell you what you should do but just informing you of the possible consequences of your actions. I am not a music attorney and this is not legal advice.
