Porcelain Heart is a bad combo of Grand Conjuration and To Rid the Disease

Porcelain heart isn't very good. The riff under the lead is the same melodic theme as the main riff in Grand Conjuration and the verses have the same melody and phrasing as To Rid the Disease. There's next to nothing tying all the parts together. No real transitions. The only good thing about the song is the lullaby style acoustic part. Why did Mike release such a dumper? Was he rushed in writing?
