It's coveted by musicians and a number of other specialty applications.
Specialty groups are rather time agnostic. The Technics SL-1200 turntable for instance (look it up, you've seen it) hasn't changed much in 50 years and Technics brought it out of retirement because the demand for used ones was so high
So a 68020 is perfectly fine for these types of things. It's not a general purpose tool, it's a specific thing just like the Technics are for hobbyist and professional "turntablists" and not meant to substitute say Spotify
Techno and electro by artists which you may have not heard of but who have prestigious awards and Wikipedia pages. Along with the Prophet, Roland SH-101, TR-808 and TB-303, the Amiga is coveted vintage equipment. (For instance, this coldwave producer: https://www.discogs.com/artist/3805670-Equinoxious ... That's almost exclusively 35 year old equipment)
Might not be your thing, sure, fine. That's not the point. There's a significant scene that uses amigas for this.
Vintage Commodores have a fanbase all on their own in the electronic music world and get featured prominently in some videos such as (1:50) https://m.youtube.com/watch?v=-UdW-lmHSNY
There's after market hardware, such as an Amiga 500 SCSI -> SD bridge because at one time old 50 pin SCSI drives were going for hundreds of dollars and people in this community started making modern retrofits so they didn't have to pay high prices for failing hardware.
I assumed that rognvald used a tracker but his Rognmashine plugin seems to run only on Max for Live: http://rognvald.com/Rognmashine.html which suggests that Live is his Daw of choice (though I can't independently confirm that.)
