My iTunes experience I mentioned below got me thinking, are there any other weirdly priced album where buying the individual tracks at 79p a pop is cheaper than the paying for the whole album in one go. Obviously this means starting by looking at albums with just one track on. I can actually only think of one that fits the bill off the top of my head - Tain by The Decemberists - 1 track of prog folk rock in a similar vain to Suppers Ready by Genesis. I great album which I already own, but I looked for it anyway. iTunes doesn't stock it, though they do have their 5 songs EP at a reasonable price.
So, onto albums with just a couple of tracks; the most likely candidates are going to be Post Rock artists such as Godspeed You! Black Emperor. No Godspeed, in fact very little in the way of Post Rock whatsoever, which is not really surprising as the genre is mainly catered for by independent Canadian labels which aren't exactly iTunes standard fare. I did spot that they have the brilliant 5 track album "The Earth Is Not A Cold Dead Place" by "Explosions in the Sky". Interesting one this, you can buy 4 of the tracks for 79p, but to get all 5 you have to buy the album for £7.99.
