I don't think it's unexpected.
Though it re-enforces the feeling that I may be part of a dying breed who values albums over singles, listeners that are usually more inclined sit down and listen to music.
As a musician, especially when writing for someone else, I realize that I somehow became conscious of the tyrannic grip of the dumber and dumber market rules - get to the point and hook your listener within the first 10 seconds or you've lost them.
No more intro, no more building up. We need a song that's Chorus-Chorus-Chorus-Alt Chorus-Chorus-Chorus.
Some artists undoubtedly filled albums with sub-standard material and got their platinum album on the sole merit of a hit single or two. But in many cases, the album provided an outlet for the artists to express themselves outside the constraints of the hit single paradigm.
As such, there are lots of records in my collection which I enjoy from A to Z w/ the exception of the hit single.
Though it was unavoidable, it's sad to see that the age when market and artistic vision coincided a bit more - an age where people wanted albums like DSOTM, when popular music had evolved from the 3 chords cliché love song into things like Stairway to Heaven.
Remember when Uptown Girl by Billy Joel topped the charts? Man, there's enough music in there to make 20 songs by current standards... Back then, THAT was pop!
