its a good point you raise Fog , all skilled craftsman in any field are capable of and do produce dross and I actually think the smarter ones actually intentionally do so to keep you guessing or themselves guessing given I believe most song writers at least initially write for themselves rather than an appreciative audience or otherwise notwithstanding some clearly craft a formula that strives for success in terms of sales etc.It’s how I think about them because 1) I like their individual songs better than the records they’re on and 2) for a good portion of their early life they were like most other bands a singles band. With their genius was some outright dross that was included on their records — Pepper has some and The White Album has plenty.
Also sometimes people are wrong, though not about Rubber Soul and Revolver probably. But I mean they’re the most influential rock band in history — so no matter what I think of their records song for song you kind of have to include them near the top for sheer importance. But as collective unified thematic works of art I don’t find their albums as compelling as those of many other bands. If I were to pick only one it would probably be Abbey Road, because I like the songs the best, not because there was a thematic element to it or because they had something important to say.
I really don't think writing poor songs and songs that are not popular should be discouraged for if nothing else it makes you appreciate the music you enjoy even more so.
the beauty of music is every piece written has an audience.
Its clear to me at least your tastes and varied and many and perhaps if I dare say both of us may not be into the commercially attractive songs as much as many others are at least in my case that is so be albeit their would be many songs I enjoy listening to that you would give a wide birth and for good reasons.
