In this day and age, bands always releasing cd versions that differ only by one or 2 bonus tracks perplexes me, especially if there's not too much difference in price.
Back in the day, when sales were split equally across vinyl, cassette, and cd, I could see why one of the versions might have a bonus track or two, probably to encourage purchase of that medium. But in today's world, I don't understand the thought behind it.
I've never not bought the version of a cd that has bonus tracks (included DVD, that's another story), so I'm curious as to why someone would choose not to these days if both are available to them.
(I have noticed a trend where iTunes releases and the like sometimes come with unique bonus tracks, but I don't mess with that.)
