I just tried the free version and I'm pretty impressed with the results.
However, after some testing I notice that when I add files seperately (instead of adding a compete folder) the Auto Correct does not work at all.
Jaikoz starts searching but no matches as a result.
I clean ALL tags (in case this could be a problem) but with the same result...no matches.
However, when I add a complete folder. The Auto Correct works perfectly.
Its unclear users usually report the opposite. But it is best to match whole folders anyway rather than trying to match single songs, this is much more likely to result in getting the right album as well as the right song.
