Odd-numbered years better for prog?

Looking through my collection, I noticed that most of the best prog and jazz/fusion albums came out in odd-numbered years. That's not to say that great albums didn't come out in even-numbered years, but there is a substantial difference. This is especially apparent in modern prog, years like 2005, 2007, 2009, and 2011 seem to have a lot of great albums released by various bands and artists, much more than the even numbered years. 2013 seems to be heading that way too.
Anyone else notice this and can comment?

This applies for my music library. Nice find. 

1972 figures stron in the PA top ablums chart

Indeed

Years beginning with 9 and 7 would then be before the crusades?

The Crusades.... man those were the days....

The Mayans. I blame the Mayans.

I would agree with this theory, at least in the 21st century. 05, 07, 09, and 11 were great years for prog albums, IMO.

Do another list and include odd-numbered albums, and we'll compare. I could, and so could you. But there is no reason to do that - the point I was making, (and I think it is made sufficiently as to not require any further examples), is that there is no odd-even correlation at all. And if it doesn't work for the 70s then why bother with the other decades? Originally posted by darkshade But also: Originally posted by darkshade That's not to say that great albums didn't come out in even-numbered years And when there is an acceptably balance between even and odd year-numbers in the Top albums then it is safe to assume that if we measure good years by the number of great albums then, again, there is no odd-even correlation at all.   When there is not logical explanation why there should be a correlation then any perceived correlation will be in question.

Dean's right. If there were anything to it, why would it not apply equally to the 70s? It sounds perhaps like a streak. Even if there were a genuine imbalance, streaks happen. If they didn't no one would get excited about gambling. But I'm not convinced there's any skewing at all, because there's no method of arriving at inter-rater reliability. What gets counted or not counted is simply subjective.
