My friend made fun of me when I told him I only make concept albums - as if a "concept album" is simply some weird experimental leap at trying to tell an entire story through a series of songs. But, what's the point of an album if that's not what you're doing? Giving your listeners a small price-point break? 14 songs for $10 instead of $14 to buy those $0.99 songs separately.
But how many of those songs do you really love? 1 or 2 on average? Just buy the singles. Because with most bands, there's no bigger story being told. Of course, if you want to learn the entire story of the prodigal son, you better buy the whole thing.
