Sure you say that you'll buy the album after you download it but there are loads of people out there who would just download the album and that's the end of that. First you download it, then someone else downloads it off you and so forth. How many of those people down the chain will actually buy the album. The band worked their asses off writing these songs and recording it. It's not about being rich and famous, it's about at least getting the respect from their fans to have the patience to wait for the arrival of the new album. They hardly make any money off the album sales as it is. For some of them, their previous day jobs earned way more money than being in the band. They could easily just say, "Fuck it" and just go back to their day jobs. Their efforts into this album or any other is way more than you waiting a measly few months or even a year for it. So give them a bit of respect.
