I feel like it would do a lot better if she went by Stefani rather than Gaga. Can't see Jazz fans running out to buy a Lady Gaga album, even if Tony is there.
Let's see. If half the people who bought ARTPOP first week + Tony's fanbase that won't be turned off by the album being a collab work with Gaga buy ctc first week, then the album should sell around 129K first week. Not bad.
