Azeroth's Top Twenty Tunes

You must be Level 100 with a Level 3 Garrison and have unlocked the Garrison Jukebox by completing the introductory quest Bringing the Bass before any Music Rolls will count toward this achievement.

The reward for completing Bringing the Bass is the Stash of Dusty Music Rolls, which automatically provides seven rolls: Music Roll: Curse of the Worgen, Music Roll: Exodar, Music Roll: Gnomeregan, Music Roll: Ironforge, Music Roll: Night Song, Music Roll: Stormwind, and Music Roll: Way of the Monk — all seven count toward the achievement.

You need 13 additional rolls from the remaining available Music Rolls to reach 20 total; you only need 20 out of the 31 available rolls, so target whichever are most convenient for you.

Obtain Music Roll: Magic at 56.5, 49.5 in Ashenvale.

Obtain Music Roll: Mountains at 68, 73.9 in Winterspring.

Obtain Music Roll: Shalandis Isle at 43.01, 75.67 in Darnassus.

Several rolls drop from raid bosses you can enter and defeat solo: Music Roll: The Burning Legion drops from Illidan Stormrage in Black Temple, Music Roll: Legends of Azeroth drops from Nefarian in Blackwing Descent, Music Roll: Heart of Pandaria drops from Sha of Fear in Terrace of Endless Spring, Music Roll: Wrath of the Lich King drops from Kel'Thuzad in Naxxramas, Music Roll: The Shattering drops in Dragon Soul, and Music Roll: A Siege of Worlds drops from Blackhand in Blackrock Foundry.

Music Roll: Cold Mountain is obtained by fishing in Ironforge.

Once you have learned any 20 Music Rolls in total, the achievement will complete and you will receive the Portable Audiophone toy.
