My point was that if you really do want to keep making music with Punchline, you can do so even if you don't hit number 1 on itunes (even if you probably couldn't if the songs don't sell anything). Its a false dichotomy and it seems wrong to abuse it.
But you've obviously made up your mind about this. So even though I don't necessarily agree with the move I'll still wish you best of luck. Hopefully for your sake you'll hit number one without alienating much of your current fan base =) Given the response of a lot of the people on this thread, your fans seem fairly supportive so you probably have nothing to worry about
