I think these are only half truths. Gigi was involved with many producers. They gave him demos, but he also added his skills to the finished songs.
I can't believe that Gigi would just buy songs.
It is interesting, however, that many songs were released with only Gigi as the author, when we know who else were co-authors. What was the need for this? And this may be the reason for the conflict with many of his older co-authors.
In the case of Stefano, there are about 20 songs whose authors are not listed on the CDs. Example : Bisogna Lavorare, Distorsione Dag …
There were about 100 comments under the TikTok video and someone wrote that Mauro Picotto's songs were also written by others and compared him to Gigi. It's funny to think, since Mauro was an author or producer on at least 1000 vinyl releases... If he's not a good musician, who in the world is? 😂
