I found the Musc Collection to have little, if anything to do with the EdT. It was all berries and iris over the original musk from the "Musc for Him" oil.
It is an interesting fragrance though. Best part is that it doesn't have the fungal quality that the EdT has. Worst part is that it doesn't have the cucumber-melon-patchouli-concrete vibe that the EdT has.
