Nothing quite says fluff piece like the tried and true "Top 10" list. The "Top 10" list combines the pointless regurgitation of common knowledge with a ranking system. This helps to not only extol the author's perceived intellect, but to attempt to create a small sense of controversy to promote talk of the publisher of the aforementioned list. That said, I have compiled a list of what I view to be the best anime OPs to grace the 80s.
The first few titles that will be covered are the bastards among this list. Yes, these first few contenders are the honorable mentions, though the term is not used in the strictest sense. These titles all would have easily made the list, had it not been for one small problem: none of these are actually openings. These all take the form of insert songs or ending themes, and were thus ineligible (under my arbitrary stipulation) for the coveted and few ranked positions.
Here is a brief interview with Ichiro Itano about Macross F, translated by "それも名無しで !MQOpFj.OVc" of /m/.
Interviewer: So we're planning a page for fans who don't know you (Itano) or the original Macross.
Itano: Macross Ace (the magazine this is in) is a damned bishoujo character magazine isn't it? I call it "yutori"*, though. Yutori character moe magazine. I think Macross (the original) was popular because of its balance, 1/3 each of cute girls, robots, and songs. But now they say mecha won't sell, robots won't sell, so they turn it into a character-based anime AND they want the fujoshi. I hate the stench of that sort of thing and so actually don't want to be in any magazine articles related to that bullshit, but I said I'd cooperate if they let me badmouth shit and here I am.
