I just found this, it looks ok but there’s not much info about it on the web. Interface and the UX are right up my alley. Lots of metadata sources and ways to edit which is great. I have the trial, but it’s only 3 days and limited. Before spending 23 euros on it I would like to know if anybody knows about this?Cheers 
IMHO The less you use 3rd party APPs for library management the better for your overall collection owes, not just Denon but all hardware and software. Put in the work and don’t rely on shortcuts. That’s just me.
I get your point, but editing metadata and artwork for larger libraries is just such a hassle.
To be honest most DJ apps are not sufficient for advanced library management. I miss integration with online databases for metadata. being able to compare files, check if a file is really a flac and not some transcode. Apps like Picard are a bit too cumbersome in UX and UI for me.
I can’t see it getting itself out of a niche unless it offers a Windows version
It’s not.
There are great free tools like MP3TAG that make it easy, plus being on top of your collection as you ingest music reduces the “hassle”. Just put in the work.
I DO put in the work, thank you vey much. I am always on top of my collection, not some lazy newbie who wants everything done for them. I Still consider it a hassle and am entitled to my opinion on it.
Fun thing: Mp3Tag for MacOS is a paid app, the Windows version is not. It’s the same price as this app…
Ok, so I did some checks, this is 90% sure a vibe coded app. And not a very good one, it gets slower and unresponsive after a bit of use. I can hardly believe I fell for this, usually I am pretty good at spotting ai-slop. Oh well. Lesson learned 
.
I’m getting rid of it and switching to MP3TAG. Still I think a well-built tool with advanced analysis capabilities has a use for djs.
Check the MP3TAG forum for some bulk scripting ideas.
