Why do Bands Start to SUCK later in their career

Because early in their careers, they are writing for themselves..

Middle of their careers their fans/customers are starting to say things like "I wish they'd do more stuff like the older stuff"

Later in their careers they are doing everything like their "old stuff" and given their fans what they wanted, but the fans are fickle and have become bored.

I've always found that there's truth in music - some of it anyway:

This is an opinion so I need it to be taken as that. Okay, truth be told I write for me. If you like it (they have) then awesome. I like punk grind crusty sludgy black metal. Spinkle a little atmospheric/death/doom for good measure. Yeah. Matter of fact I love it. Some of my favorite bands I've actually played with. I write/play a kind of world folk gypsy punk but often its with black metal and punk bands. It so much doesnt make sense that it does. Grandparents like my band. And although they dont always enjoy the crust band we are playing with, they at least try. And that i like too. None of us ever cared if anyone liked it. We knew they did. I am not being arrogant and for the most part im still a nobody, I am stating facts. You see, they can tell when you want them to like it. And they can tell when the band knows that they will. When we take the stage I often say to my mates something along the lines of "Now lets show these pretentious plastic Ken dolls how its really fucking done."
And within 2 or 3 songs there's over 100 people dancing. On a Tuesday night in January. And my mates are smiling.

Tom Waits definitely stopped caring what people thought when he wrote "swordfish trombones" and "bone machine". Both are amazing albums that broke every genre barrier there was. And got him a few Grammy's as well.
Its not like I have a choice. I'm gonna die writing and playing music. Maybe even alone. But I did it from the heart. And boy oh boy did I have a good time.

There also is the whole Young naive and stupid, understands young naive and stupid! In other words Taylor Swift still knows what's it like to be 15!
At 30 the market of buyers shrink !

They found a black hole the density (so probably size) of 17 billion stars. To put it into perspective; 1.3 million earths can fit into the sun. There are also many stars that are the size of from Jupiter to the Sun. This black hole is the size of 17 billion. There would be nothing that us humans could consider reality even near such a behemoth.
Now what do you think Taylor Swift thinks about that?
Im sure if young Pink Floyd were around today they would've written albums about it. I didn't love the later stuff.

You got me thinking about the reason behind why people love early songs from bands/artists, but tend to love their newer songs less, even though they might be almost identical in content, and performance.

I don't think it's as much "getting bored" as I might have thought originally.

I think it's because people form attachments to certain songs due to life experiences, and we tend to do it while listening to things that we find new and interesting. 

We tend to bond to songs that got us through "tough times", etc. 

Case in point, in my early teens, I was just coming around to listening to music, mainly various forms of thrash and extreme metal.  I can think of a few instances that listening to certain songs that I liked at the time, got me through some tough life lessons.  

Now, those songs are some of my all-time favorites, even though the bands have put out far "better" records since, and have often tried to mimic those early records with their later ones.

So I think that society goes through phases, and that each generation will always have some kind of connection to an era of music, and that the later releases will always be compared to the earlier ones that made connections.

I think the main reasons are they lose the spark and their audiences don't necessarily get smaller. So they are positively reinforced for lazy music and travel up their own asses.

Sad to say, but the best artists seem to be those who can still get down on themselves after they become famous.

Or who collaborate with new people, leaving the spotlight for a while and working with those who are not afraid to tell them what they really think.

I do agree that sometimes artists do evolve for the better and original fans are just stupid or only care about hooks.

if I understand correctly, it took J Lennon 7 years to finish writing Strawberry Fields Forever, if you check out youtube, you can find a slew of classic tunes that were apparently under construction for quite some time.

I know clever and talented chaps but they even never had something like a career, and they don't fell sorry for this.
In other words - place 100 can work a lifetime - number one gets hard one day.

George Martin has said or possibly even said to me when we met that if they'd had Pro Tools, they'd probably still be working on Sgt. Pepper's!

I think sometimes bands, just like anyone else, can fall into a creative rut or get caught up in a routine. Maybe the pressure to recreate the magic of their early work hinders their ability to experiment and take risks.
Speaking of career pathways, I've been contemplating a switch myself and recently stumbled upon some intriguing info online. I came across this website on how to become a mobile locksmith, and it got me thinking. It might be worth checking out if you're open to exploring different career options.
