Any file that is added to iTunes goes into the Main library.
From there is must be manually moved to a Playlist of your choice.
The "Recently Added" folder is a "Smart Folder" that is set to show all the tracks that have been, wait for it, Recently Added to iTunes.
There are a number of these "Smart Folders" in iTunes. 50's Music, 60's Music, 90's Music just for starters.
Every piece of music that you have in iTunes is stored in the Main Library. All those other folders, including the one that you made for your vinyl converts, don't actually contain the tracks, while they will show you what is in there, it is just an indication and a pointer to the actual files location in the Main Library.
For instance. Let's say that you have a track by Patsy Cline from an album called The Patsy Cline Story. You also have a Smart Folder called 60's music, another called Country Music and another called Cline Albums.
You would find that your only track by Patsy Cline would appear in all 3 of those folders but yet you would still only have the one track.
The fact that you move your tracks out of the Recently Added folder into another one, does not change the fact that the track you moved is a Recently Added track, which is why it is still visible in the Recently Added folder.
If you were to make a Smart Folder and adjust the criteria to the vinyl you were converting, you would find that all your tracks would be in the Main Library, the Recently Added list and the Smart Folder you created.
You cannot remove things from the Recently Added list, tracks will disappear from there by themselves as you add more tracks.
Nothing wrong here.
I use a USB record player to send my record files to Itunes using a app called EZ vinyl/tape converter. I went in Itunes and mad a playlist that I wanted the songs to go int, but they never go into the playlist folder I want them to. Instead they go into a folder named "recently added". Then I have to drag the files into the playlist I made originally. Looking for an answer. Also, after I drag all the files to my playlist folder, I can't delete the files that sit in the "recently added" folder. I guess I could delete that folder altogether then make another folder with same name. As you can see, I'm new to using this app.
