It's been very rare that I've disliked any ARR song that has been longer than 6 minutes. Almost all ARR songs long in duration (greater than 6 minutes) have been exceptional to me. What does duration/length have to do with it?
With a long ARR song, there is more room for musical experimentation, elaboration, longer musical interludes....more space for creative freedom musically. That's generally how I see it. Now, the opposite does not hold true necessarily.....that shorter ARR songs are less likeable.
