It's difficult to say if it's popular. There are so many works out there. While Peter Gabriel has a large fan base, this particular work 'We're Back! A Dinosaur's Story' may not have reached mainstream popularity. It could be that it's more of a cult - like favorite among certain communities who appreciate the unique combination of music and a dinosaur - based narrative. However, without more data on its sales, streams, or public reception, it's hard to determine its true popularity level.
Well, popularity is a relative term. 'We're Back! A Dinosaur's Story' might not be as well - known as some of Peter Gabriel's more famous albums. But for those who are into both his music and dinosaur - related stories, it could be a real gem. It may not be getting the radio play or mass media attention that some of his other works do. However, in smaller circles, such as among dinosaur enthusiasts who also love Peter Gabriel's music, it might be quite popular. Maybe it has been shared and talked about within those specific groups more than in the general public, so its popularity really depends on which audience you consider.
