Those are most probably autogenerated spam results((a)

autogenerated mp3 spam results).
Maybe you've already d/loaded some of those fake files and that's why it's showing as already being d/loaded.
Be sure to check file sizes before you d/load something. Those fake files are usually smaller then 1MB(1000KBs). Most song files are at least 3MBs(3000KBs). Don't d/load anything smaller than 2MBs.
