I always figured that you, as the 'artist,' must strive to make a recording that you'd want someone else to make, which is what you said there, and I always told all the musicians I've ever known this: there's no guarantee that anyone other than you and me and your family will ever hear this record, so you'd damn well better make a record that you're proud of, that you can listen to, because there's a chance that you'll be one of a handful of people who ever hears it. That's a very pessimistic outlook, of course, and probably why I don't work for a label anymore, because they were always trying to get people to make commercial stuff and I was always telling people to make records that they themselves could be proud of instead of copying someone else and ending up with a bargain-bin cut-out disc that they're embarrassed to show their grandkids, or at the very least, a bunch of "what ifs" and bitter Behind The Music stories about how the label made them record a Diane Warren song when that wasn't really 'them' and stuff...
And now I'm ranting.
A musician who can't enjoy listening to his/her own music is doing something wrong. It's not masturbatory. If you don't listen back to what you've done, how can you improve? And if you can't listen to what you've done, how can you expect someone else to?
Bang your head. Metal health will drive you mad.
