Yes, I answered this for you as well. When you look at tracks in a folder you only see the file name. If you want to see all the metadata you need to bring the music into Engine Prime and create a playlist or crate.
Here is a link to Engine Prime: https://www.denondj.com/engine-prime
Here is our PRIME 4 Getting Started landing page: https://www.denondj.com/getting-started-with-prime-4
You’ll find lots of helpful info there.
you might aswell delete this topic anyhow as ive already got 1 here in the prime 4 section
That folder is just like using file explorer on your PC/phone. Kinda like a way to navigate to a specific file.
coming from Serato where i had folders and it showed the whole data its kinda annoying to see it not there now so i have to search instead for a track or just load it on to check it suppose i might get used to it or i wont we shall see.
I know the feeling of “it doesn’t behave the same as my other thing”
But different doesn’t mean wrong or worse
Also with most things there’ll often be a whole load of things that new item does better than old item and some things that old item did better or at least different from new item
Rarely does anything show itself instantly as better in every respect and every situation - that’s life, that’s technology, that’s DJing
Hang on. I thought this was supposed to be a standalone “DJ System”? Isn’t that how Denon are promoting the Prime 4?
As such, it should be capable of reading tag info in a file without needing to run the file through Engine Prime on a computer first!
You may not consider it a bug, but it’s a pretty stupid requirement for a “standalone” system.
Ok. I’m in! lol Prime 4 was in front of me… I couldn’t resist. What I’VE noticed is on the main screen where you have all of your waveforms it’s VERY easy to grab the scroll when you’re trying to swipe a song to one of your left channels. I did it about 15 times last night at a gig. Otherwise…
FLAWLESS performance from the Prime 4!!! Used everything but the zone out.
The absolute ONLY thing (and I’ve voiced this already) - I wish Denon would’ve mimicked the pad layout of the SC5000. I know different doesn’t mean worse and I can get they probably wanted all other controller DJs to feel comfortable (and especially since it’s also a serato board) but I LOVE the layout of the SC5000s. To me for cue play (which I do a lot of) the playability of the pads from left to right is just WAY better. It’ll just be a slight train for my brain, but it’s a wish for maybe the future. Your design language for the SC5000 is just perfect to me Denon! Please consider keeping it for future models.
Saying that. I will say I really like the pad feel of the the pads on the Prime 4. They take a very light touch to engage which mean rapid taps are a joy!
But again. Everything else was awesome! Loved having two XLR for my mics and I LOVE the FX layout on the Prime 4! WAY WAY better than on the X1800! So that’s a plus!
And I am still hopeful for Pitch Play!
Either Way. Happy to see Denon on a roll here! Prime 4 gets a thumbs up from me!
Sure is standalone for performance.
No performance, of hardware, software, or DJs for that matter is gonna be much cop without preparation.
And preparation is what engine Prime does - but you only use engine Prime at home for the prepare part of making your show better, when you actually perform - and that performance is standalone.
There’s no point in anyone taking “standalone” as meaning “I’ve never even touched a computer ever in my life” 
No one neeeeeeeeeeeeds the meta data but it’s a nice thing to have.
lol There is no “requirement” to use Engine Prime. However, if you want to view all of your metatag data the files need to be analyzed. This is standard process for every DJ application on the planet. We have an advantage to other hardware products on the market as PRIME 4 can analyze on the fly so you really don’t need the computer at all. For the best experience, I would recommend running your collection through Engine Prime first.
Again this is a recommendation and not a requirement.
Oh for heaven’s sake…
You do not need to run files through engine prime, though if you want more advanced features you need to prep tracks beforehand, just like EVERY OTHER DJ SYSTEM.
Prime 4 is standalone in the same way the other standalone systems on the market are.
Geez, some people…
You nailed it
You can drop any playable track into the unit without first analysing. The unit will analyse the song on load, if you want it to be analysed before loading, you gotta run it through engine prime.
This is exactly the same as Pioneers XDJ/CDJ line, and presumingly Denons SC5000/M line too, which are all standalone units. The same happens using controllers, should you not analyse the tracks first, this will be done on load.
Music doesn’t come with the full track analysed for use on any DJ software, you gotta do that yourself or load the track and let the unit do its thing. 
Engine prime not installing on PC anymore. Yeh this is going great so far lol
Hi @Ghastous, could you be a little more specific as to what ‘not installing anymore’ means.
You only need to install the application once, unless there is an update to over right the previous version.
The more info you can give us, error messages, screen shots etc the better we’ll be able to assist.
Regards J
buy a mac 
I’ve got a Mac but unfortunately it ain’t got the power my pc as .
As for the error it comes up with 0xfffffff7
Oh right, so when you said:
…you (Denon staff member) were giving out incorrect information. [sigh]
Even I understand what @JWiLL is trying to explain to you, but clearly you seem to be unwilling to do so.
English is not my native tongue, but try reading JWILL’s text again and emphasize on the word ALL…
No, all of the information I provided is correct.
Some people will deliberately ignore or twist information to perpetuate their own “stuck in my favourite loop all my life”
As predictable as hearing “Final countdown” on New Year’s Eve
