It depends upon WHY it's over 4 minutes. If the reason is because of an extended guitar solo, then yeah, I would agree (for the most part).
But some songs are just long songs because that's how long they need to be.
For instance, most of my songs are under 3:30, but I do have a couple that are over 4 and a couple more that are over 5!
Okay, I'll admit that one of those 5-plus minute songs might be a little self-indulgent. But there was a reason for that indulgence, at least in my mind. I wanted to break down the parts that I had built up in the beginning and deconstruct it before the fade. Yes, admittedly indulgent, but I also found that I was a bit entranced, myself.
So, I put it as the last song on the album, so it was easy enough to turn it off:

You tell me, if you want:

I hate (most) extended jams. Masturbatory, yes.
But an extended jam like the one in the middle of "Marquee Moon," I would argue, is essential to the flow of the song, as that long solo brings the tune to an emotional height that it would not have achieved otherwise.
WARNING -- 10-minute song!
If you do listen to all these songs, I am curious as to what you think about my points on them. If not, I totally understand. I'm not so sure that I would. That's a lot of time to devote to a single post on a message board.
