It was, but to a lesser extent. There were about three remixes of the Intro Theme, two or three of the Menu Theme, and two of the 64 Intro. As many others have said, the Brawl theme was just too overwhelming after a while. The themes in Melee were more accessible, and they made more originals than in Brawl. In SSBB, with the exception of Tabuu's theme, I'm pretty sure EVERY original song was based on the Brawl theme, which can get a little too overwhelming, especially for a song that's already a little too much for a generally lighthearted party/fighting game.
