They have them stuck in their head so much, they have to create the songs and infect others with it.
No, they can’t stop coming up with them.
In the shower washing their asshole?
“Fresh all over, don’t forget / The spots you sometimes might neglect! / Soap and water make you whole, / Stay clean and proud from head to… soul!”
I can already sing it!
First of all I don’t think there’s many full time jingle writers - let’s call them commercial composers, usually also producers at the same time. Meaning they get paid to create music for whatever occasion.
And for those, I’m fairly certain that they analyze music all the time, even while listening to the radio. They know the building blocks (they’re simple), and at some point realize what a catchy melody sounds like and how easy it is to produce one.
So, yes to your first question, though I don’t think it’s annoying to them.
I’ve known a few jingle writers, and yeah, it was always a side gig.
By now they will probably be more and more unemployed, thanks to generative AI. At least for the standard stuff that’s probably good enough by now.
Honestly, I’m still curious how that’s gonna play out. Lots of jingles weren’t the craziest of compositions so far. They’re often just a handful of notes played in succession with one instrument. That’s a big part of what makes them memorable.
Instead, I feel like companies often paid for a composer, because they needed someone whose taste is decidedly more highly regarded than their design committee’s. Someone who’s able to make a decision without twenty people thinking they have a much better idea that needs to be heard.
So, I could imagine this going one way or another.
Either the boss can now generate jingles quickly enough that they don’t delegate it. Then the decision is still in the hands of one person, although likely the hands of someone with no musical training, so I do expect jingles to sound worse in that scenario.
…Or everyone in the design committee brings along a dozen generated jingles, the decision paralysis is magnitudes worse and they have to bring in a composer anyways.The first wave of displacement was licensing - all those car commercials with Springsteen tunes.
Jingle writers are professional ear worm avoiders. They know that to end an earworm, you need to listen to an even more catchy tune.
Mahna Mahna is my mental pallet cleanser.
My brother used to do this in the 90s. No, but he was always writing and playing something.
No because they aren’t annoying to them, to them its just what they precieve as an inner monologue
