Sugestion on importing songs

[yamezbond]

Hi,
I have rebuild my database since last Friday, however I mess up when I was imported some files. My problem was that I was imported around 3000 songs ok, but I get messy with 100 songs. I get to the part of checking the songs so I can delete but I only have the option to find the most recently songs I added or the 1 day songs. So guess what? I ended deleted the 3000 songs from the database because all the songs came on the list. I wonder if there is or you guys can add some options like find files added 1 hour ago or somenthing, that way I cannot re-due all the import.
