UGH….deleted all songs, not just the duplicates!

Not sure what happened but after scanning itunes, it came up with duplicate songs and I carefully deleted the extra copies. I tested with just a few songs. AVG Cleaner put them in my trash (good) but when I emptied my trash, ALL COPIES of the songs were gone. At least it was free and I can re-download my songs but I had to uninstall.
