Top 20 Slayer songs for your International Day of Slayer playlist

Slayer in 1986. 

To commemorate the sixth annual International Day of Slayer - which, if your math skills aren't so great, originated on the incredibly appropriate date of 6/6/06 - I have decided to assemble a playlist of 20 of Slayer's greatest songs.

I should note right off the bat that this isn't a "true" Top 20 list of Slayer's absolute best songs. My goal was simply to create a career-spanning playlist to celebrate the International Day of Slayer. In so doing, I established the following two rules for myself:

1. I had to choose at least one song from each of Slayer's full-length studio albums (I didn't include live albums or EPs, but I did pick a song from their album of punk covers, Undisputed Attitude).

2. The total running time of the playlist could not exceed 80 minutes - the duration of a standard CD-R.
