Garrison Jukebox
The Garrison Jukebox, known as the 
B.O.O.M. Box or 
Tune-O-Tron 5000, is a feature added in patch 6.1, that allows players to change the music that plays in their Garrison.
Unlock the jukebox by completing 
[40] Bringing the Bass, which requires gathering five items from all over Draenor. After gathering the five items, the jukebox is built and players are handed seven music rolls. Interact with the jukebox to have it play the requested song instead of the default garrison music while at the garrison.
For the sophisticated character who cannot stand silence while out and about, a 
[Portable Audiophone] toy is awarded for completing the 
[Azeroth's Top Twenty Tunes] achievement, which requires learning 20 music rolls.
Music rolls
Completing the initial quest rewards the 
[Stash of Dusty Music Rolls], which contains seven music rolls for the character's faction:
- Alliance
- Horde
Other rolls
Many other rolls are found all over Azeroth, Draenor, and Outland.
Hints
The quest-giver next to the jukebox also gives some (faction-appropriate) hints.
- ^ A Siege of Worlds: You're already leading a campaign against the Iron Horde. Might as well take Blackhand's music roll collection while you're at it.
- ^ Cold Mountain: Got a rod and reel handy? I hear there's an artist leaving her work in creative places in Ironforge.
- ^ Heart of Pandaria: Conquering fear itself will help you glimpse the Heart of Pandaria, musically speaking, of course.
- ^ High Seas: Lion's Landing has a track as fresh as the sea. Watch out for sharks!
- ^ Legends of Azeroth: Deep in the heart of Blackrock Depths is a track so legendary, it takes two dragons to protect it.
- ^ The Burning Legion: Up for a journey into the Black Temple? You still won't be prepared for the hard hitting bass of the track you'lll find.
- ^ The Shattering: Finding classic tracks takes hard work, and sometimes that means flying on the back of a colossal, cataclysmic dragon. Them's the breaks.
- ^ War March: Feeling a song of war? Domination Point in Pandaria used to shake with heavy drum beats
- ^ Wrath of the Lich King: Face his wrath, in that flying fortress, with that icy weather? All for new music? You're crazy!
