Duplicate Songs

I don't recall how I ended up with multiples, but it was probably when I migrated my library over from my desktop to the current laptop.  I had posted here a couple of times during that process seeking help and somehow wouldn't up with multiples.  

I looked into when and each multiple was imported, but each tracks import date seemed different than other multiples, not allowing for me to find any common import date amongst them all.

Regardless, I manually sifted through my entire library and deleted all the unwanted multipless leaving me with only singles of each track in my library. hurray!!! It took weeks - no joke! What a stupid system. This seems flawed to me but whatever I'm sure you'll eventually find some quicker solution (or not)

Regardless the work has been done, however (surprise surprise) I have a new problem! On my laptops desktop, I have a 'DJ Music' folder that has all 5600 DJ songs (no multiples) as my Master Copy.  Currently in Rekordbox I have 5100 of these songs.  I'd like to get the remaining 500 songs into my Rekordbox Library (just those, no multiples) but they are scattered  throughout the folder and I cannot remember them all therefore not easily found.  Is there a way for me to import just the unsynced 500 songs from the DJ music folder?  Or is there another way to set up Rekordbox so I can ge those 500 songs? Maybe synced to my iTunes? 

Thanks in advance!

Just re-import that master folder and anything already found in the collection will be skipped.

OK so I tried what you said and re-imported the folder - it just starts syncing all 5600 tracks.  I quickly stop it but now I have to comb through my library AGAIN and delete the doubles as they are scattered throughout.

Yes, it will count the total but only add those which are new.

You didn't read what I wrote above - it syncs songs. Again, I had about 300-400 doubles before I stopped it & I had to comb through my library, find and delete again. 

And having used rekordbox since v1, I know how it works -- if it's creating duplicates, you have moved or copied music on your drive(s). Re-adding the same folder will only add new music from that folder to rekordbox. Any existing songs are ignored, so if you are finding duplicates, take a look at the path of the song to determine why there are now two copies.

I certainly hope you used your own product since the beginning - what an absurd comment. I've been using your software for years as well and CONSISTENTLY had problems...almost every DJ I know in the industry has problems with your software - What does that say? You've even admitted to me elsewhere in this forum that you help rebuild superstar DJ's libraries because (gasp!) the have problems with your software too. 

Going back to how this whole clusterfuck happened, I was corresponding with you about migrating just my DJ music from my desktop iMac to a new Macbook (to use with my purchase of a DDJ-800) as surprisingly, I couldn't find any clear info on your website on how to do this process.  During a vague and extremely unhelpful forum troubleshoot conversation, I tried everything on my end to get my entire DJ library to show up on my Macbook and eventually ended up with most of it (80%). While I'm no superstar DJ, I'm still a working DJ who gets paid and at that time was heading into the fall/Xmas season with multiple gigs each month lined up, I decided to 'make due' with the library I had as I needed to DJ these shows.

Since all that went down, I cannot say when, where or how I got most of the music onto the Macbook. Most of the clear concise info you gave to me was after the fact and my searches into song paths are confusing at best.

What I do want is a functioning music library. If possible - I'd like to keep all the saved cue points, playlists, etc. that I've made on my tracks on the new Macbook but I also want a functioning music library that doesn't keep having tracks disappear (orange exclamation marks), thousands of duplicates, etc.

What is the best way forward? Is there a way to delete my entire library and start fresh (a new import with all my music coming from a single source) but still retain a number of playlists with cue points, track info? 

The best and easiest thing to do to move to another computer is to backup the database (File > Library > Backup Library) then on the new computer, restore it (File > Library > Restore).

The music files should be copied over from one to the other, maintaining the structure they're in now. Chances are they'll ALL be missing, but the process of doing a mass-relocation will take just a couple of clicks and would only need to be run once because the only difference between the old computer and the new computer is likely to be the name of the drive or the user, the rest of the path remains the same.

If you aren't using iTunes, allowing it to manage the music file location, and you're not using an external drive which may get mounted as different volume / path, and you're not moving the music around yourself, rekordbox won't lose the music.

And good news - if you happen to move to rekordbox 6, and still do any of those things in the last paragraph, the auto-relocate function can quickly and easily find the missing files for you.

You can have multiple songs just by dragging a song again to the playlist. RB will ask if you want to ADD or SKIP. Normally I press "SKIP", but there is a option to ADD. By that RB is allowing have multiple songs. Now the question is how easily we can remove those songs?

@Felipe > Those aren't actually duplicate songs just duplicate entries on the playlist. My recommendation there is to sort by name and manually remove the duplicates you no longer want to have in there.

Traktor offers this feature for feature for "centuries".

Of course, Traktor is a way more advanced software compared to Rekordbox, but I am sure, a big company like AlphaTheta Corporation from the technology leading country of Japan should be able to code such easy features as the Berlin guys do... :-)
