I see absolutely nothing wrong with Mike's assertion regarding the length of an intro, either specifically or in general. Having the opinion neither makes him right or wrong. Indeed, within the pop song market especially, it is a commonly held practice to get to the singing as quickly as possible. By all means disagree with the opinion, but it is a valid opinion.
As to Iron Maiden, big rock hit or not... who is to say it might not have been a bigger hit had the intro been shorter? Equally that suggestion could well have ruined the song and made it not a hit, as I suspect Rob and other rockers might assert, rock does love a longer intro than pop. Apples and oranges. By all means debate. We put forth our best rationale and we try to work out our differences, or make our case.... but it is the OP that decides what to apply to their song or performance, and what they consider right for it or not.
Of course we all form an opinion, and have a degree of conviction as to what we would have done... but it is not our song, or our performance. In this we are all advisors offering opinions.
Should you find you disagree with Mike's perspective you can of course disagree with that opinion at any point. Even have a general discussion about the pros and cons of intro lengths.
As for how that opinion is expressed, that is a different matter, though it is still subjective... I do really appreciate that we all try to police ourselves and to effect change. Sometimes saying "You were a bit harsh" or "that came over as really dismissive" etc can go a long way. If you really think someone is way over the line, ask for a mod to review the offending post. That's what we are there for.
We are all adults and I do want all members to feel they can express their opinions (with the exception of personal attacks and other rule breaking stuff) but staying on topic in review threads is important too. Arguments happen, but mutual respect is also needed. Balance in all things.
I am not sitting in judgement of anyone here. No one has asked for a moderator but I can see the thread is a bit heated at points and all I would suggest is that you shake hands and remember we are here for our love of music, take a deep breath, have a hug, whatever and put the thread behind you.
In addition, if you want to discuss suggestions and points further, let's start a new topic away from the OP post where we can discuss the way we express our opinions constructively. That would certainly be a constructive, healthy way to effect change with a minimum of pissedoffness (another word invention). If it means a rules or guidelines update, so be it. At least we then all have more clarity on something that is a bit woolly.
I would point out that text communication can be misconstrued, especially humor. Text lacks many social cues that face to face conversation already has built in. Brevity can come across as short, like a put down, flippant. Humor can come across as insulting, or even cruel. That doesn't mean you cannot be brief or use humor, simply that awareness is your friend and a little more care than usual is a good idea.
Members reading this thread, and this reply, will have varying degrees of experience. To that end I have to cover as many bases as my sleep deprived brain can muster. So please forgive me if I have misunderstood, missed a point, a detail or have proceeded to make a mountain out of a molehill.
This thread has definitely wandered off topic.
Peace, hugs and stuff
