While walking to Tower Records, I was thinking about how the Smiths and New Order each released several singles in the '80's that were not on albums. Why doesn't anyone do this anymore? True, the market is very album-based now, but it was in the 80's as well. The discrepancy between the prices of albums and singles is small on our side of the Atlantic, and is large on their side. This explains, for example, why bands in the UK will release many singles before finally delivering the album. It doesn't explain why all the singles eventually turn up on albums.
