Overboard production or overproduced is what they call an album that isn't rough, layers of guitars/vocal harmonies/electronic drums and is basically perfect note for note with no obvious mistakes left in. Most Heavy Metal fans use the term to trash the album as it's more pop sounding than the bands first three albums.
Yeah they still don't have a deal with Universal for their back catalog being offered on streaming/digital services.A few re-recordings, Slang (which the band has the rights too) and their 2015 album are the only ones available digitally so far.
