All merged.
Top one is registered under the actual artist.
You don't need to specificy this every time, since it is not the criterion which is used for merging anyway, since it does in no way indicate that it might be the original file that we'd like to keep. On the contrary, in the first of your three posts the module registered to the actual artist actually contained some additional sample text added by a BBS, so it's definitely no the version that should be kept.
