Rekordbox and import songs

In the Collection, add the "Date Added" column and sort on it (right click the column names to select more columns if you don't see that).  Another way to do it: create an intelligent playlist with a rule on the 'date added'.

Thanks but the problem remain if in the same day I add songs for 2 or 3 times.

Yes, there you have a point.  For that I have created a custom category in the "My Tag" section.  I called it "Tagged".  For each  track in my collection which I have processed, I set a check for this custom tag.  And then, you can create an intelligent playlist, filtering all tracks NOT having that Tagged tag :-) Those are the ones you have imported without doing something with it.  That's a little workaround.

Thanks for your advice.

I remember that in rekordbox 3 you found automatically the latest imported tracks at the end of collection list.
