That's the 2013 gnirpz's essentials in order, following the releases along the year. Every ranking should be based on production quality, originality, musical technicality and specs like that.
Unfortunatelly, mine is based on headbanging, taste of beer, air guitar and air drum solos.
2013 feelings, form best to worst
Have a good year!
