That's exactly what I saw.
And I don't think people are reading too much into it, but they're not comprehending what they're reading.
Playing for the love of music as opposed to playing for money is a common, clear cut request. Simply put, it means someone is looking for people who are self supporting by means usually other than music, and aren't going to complain if they don't get paid. And there are a lot of musicians out there who fit the part and are willing to this. It's an understandable request when it's a band creating music together. This guy, however, wants you to learn HIS songs, note for note, quickly... and do it for nothing. And if somewhere down the line you disagree with him on something, regardless of how much time and effort you put into it, he'll find someone esle.
Run from these people. This is experience talking. You can find the same people who will pay you. Happily.
