Producers suck in general.
I think they should say, you got it, so do it, which is usually the case, or you don't so I'm not interested. But a simple phrase like 'a faster tempo' should get a bass amp thrown at any one of them.
I for one, even if the only one believes that these people at least had all the tools for the craft, and that outside influence never did a bit of good if it changed song, and in more cases makes it not as good. It's not at all like a composer conducting, It's a single opinion that is usually out of line. If a group is contracted to a performance, say a sound track to other media, that is of course different, but for a group building it's album, that's silly, unless needed. With the Beatles, it was not needed. That's why I like the 'garage' versions better than the masters in a lot of cases.
