and it could still be worse… like i said, technically every single image macro is copyright infringement. and to your question, which I’m sorry, i don’t care about, it’s not what i was replying for, it really depends. performing another person’s song for money is actually a big deal and illegal. so yeah, in your example that’s a very very easy case. weird al is a great example of what you need to do to differentiate. cover bands are often a grey area, but can be gone after, it’s just often easy to get away with.
