Yes, the relentless re-issuing of existing music is annoying, but it is by no means limited to indie bands. Look at Buddly Holly, for example. He released 5 albums before his untimely death, and that music has been re-packaged dozens and dozens of times. In fact, according to AMG, since his final studio album in 1964, the only years that have NOT seen at least one Buddy Holly compilation album are 1973 and 1976. The Doors and Jimi Hendrix catalogs have been similarly abused. I wonder what business case drives this behaviour. I can readily understand that there is still a market for Buddy Holly among younger people who are hearing some of his songs for the first time. But how can it make sense to continually create new packages containing those same songs? Why not keep selling the existing catalog plus one or two well-crafted compilations for the casual listener?
