Executive Meddling: The possible reason why their 5th and 6th albums sound so generic to some.
The band themselves heavily imply this, and it's cited as part of their reasoning for releasing their music independently. Most people believe that Hurricane and Verses are a bit better than the two previous albums as a result.
Vice Verses faced executive meddling because even though their own label is independent, it's still part of an umbrella company that helps keep it in business. Verses sounds even more generic than the previous two albums.
