I hope they don't release a single. I want to listen to the album as a whole for the first time. However, I don't have the discipline to refrain from listening to the single if they release it
See, to me, this is your problem, not anybody else's. I don't mean to sound harsh, but if you don't have the discipline to refrain from listening to something you don't want to hear, maybe you should work on your discipline. Because there are people who
do want to hear a single before the album comes out. Why should they have to miss out just because you lack self-restraint?
I think it makes a lot more sense to release a single (and snippets, and whatever else the band is comfortable releasing ahead of time). That way, everyone can make their own decision about whether or not they want to listen to it.
