This year, 457 Pazz & Jop voters submitted their Top 10 albums and singles. With albums, they have 100 points to divide among their Top 10 picks, with each entry receiving no more than 30 points or fewer than five. There's no point-ranking system for the singles category, which remains amorphous, comprising individual songs, re-mixes, downloads, viral sensations, etc. Literal release dates aren't binding, but a record or single's “impact” should have occurred primarily in 2013; in most cases, if it got votes in 2012 and 2013, we combined the two totals. It's not as complicated as it sounds.
