The album debuted at #21 on the Billboard 200 chart with 33,740 copies sold in its first week.[2] This makes Metalocalypse: Dethklok’s The Dethalbum the highest charting death metal album ever. The Dethalbum was also streamed 45,000 times when it went live on AOL Music during the week of its release.
