I am pretty impressed with the fucntionality of this software, and I'm eager to pull the trigger and purchase the pro version, but there is one issue that is a blocker for me. If I have the same song in 2 different places on my hard drive because, for example, it was on multiple albums, and I want to delete the duplicates, then i want the tags to be updated accordingly. My understanding (although i'm no expert on audio file formats) is that IDv3 v2.4 supports multiple values for each field. If the tags could be merged and stored into the one file that I do keep, I would buy the software instantly.
Problem is, I don't want to pull the trigger and delete all my duplicates as it stands, because then I will lose all the information about the other albums which the songs come from.
Does this feature make sense? Would it be difficult to implement?
