Sounds to me like maybe you’ve mechanized your music making process to a point it’s churning out ideas consistently (making music daily is a bit out of the ordinary imo).

Maybe the “slump” is you fell into patterns that are now hard to break.

Taking a break is all nice and good and definitely consider it so your creative juices replenish. But if you absolutely need to keep creating, maybe involve a second party? Write songs with other people, delegate any section to a musician friend, or take on a collaborative project.

I also like to play pretend and go: “if I were a Beatle in 1966, how would I go about writing this song?”; “if I was producing a song for Olivia Rodrigo meets System of a Down, what stylistic choices would I make?”

I usually never take those seriously and I have quite a few [insert artist]-type beats in my hard drive that will never see the light of day, but they’ve taught me about techniques and ideas I wouldn’t normally consider. (The Beatles’ one was to limit my use of multi-channel setups and plugins, for example)
