Picking a random entry out of a table/list?

I have this code in a weakaura that plays music during combat when bloodlust is cast:

Lua Code:
  1. local G = 0
  2. G = GetCVar("Sound_EnableMusic")
  3. SetCVar("Sound_EnableMusic", 0)
  4.  
  5.  
  6. if UnitExists("boss1") then
  7.    
  8.     local bossHP = UnitHealth("boss1")/UnitHealthMax("boss1")
  9.    
  10.     if bossHP > 0.8 then
  11.         local R = 0
  12.         R=math.random(1,38)
  13.        
  14.        
  15.         if (R == 1) then PlaySoundFile("sound\\01-Rising-Dragon.ogg", "Master") elseif (R == 2) then PlaySoundFile("sound\\02-Cometh.ogg", "Master") elseif (R == 3) then PlaySoundFile("sound\\03-Gothams-Reckoning.ogg", "Master") elseif (R == 4) then PlaySoundFile("sound\\35-Hunt-Or-Be-Hunted.ogg", "Master") elseif (R == 5) then PlaySoundFile("sound\\06-the-battle-is-to-the-strong-2.ogg", "Ambience") elseif(R == 6) then PlaySoundFile("sound\\06-the-battle-is-to-the-strong.ogg", "Master") elseif (R == 7) then PlaySoundFile("sound\\FFXV-1.ogg", "Master") elseif (R == 8) then PlaySoundFile("sound\\07-Kakuzu.ogg", "Master") elseif (R == 9) then PlaySoundFile("sound\\07-The-Fire-Rises.ogg", "Master") elseif (R == 10) then PlaySoundFile("sound\\08-Prominence.ogg", "Master") elseif (R == 11) then PlaySoundFile("sound\\19-Steel-for-Humans.ogg.ogg", "Master") elseif (R == 12) then PlaySoundFile("sound\\10-Fear-Will-Find-You.ogg", "Master") elseif (R == 13) then PlaySoundFile("sound\\10-Silver-for-Monsters.ogg", "Master") elseif (R == 14) then PlaySoundFile("sound\\13-Imagine-The-Fire.ogg", "Master") elseif (R == 15) then PlaySoundFile("sound\\15-Divinity.ogg", "Master") elseif (R == 16) then PlaySoundFile("sound\\129-truth-behind-the-project.ogg", "Master") elseif (R == 17) then PlaySoundFile("sound\\16-tatakau.ogg", "Master") elseif (R == 18) then PlaySoundFile("sound\\17-No-Stone-Unturned-2.ogg", "Master") elseif (R == 19) then PlaySoundFile("sound\\17-No-Stone-Unturned.ogg", "Master") elseif (R == 20) then PlaySoundFile("sound\\35-Hunt-Or-Be-Hunted.ogg", "Master") elseif (R == 21) then PlaySoundFile("sound\\19-a-chaser.ogg", "Master") elseif (R == 22) then PlaySoundFile("sound\\FFXV-4.ogg", "Master") elseif (R == 23) then PlaySoundFile("sound\\35-Hunt-Or-Be-Hunted.ogg.ogg", "Master") elseif (R == 24) then PlaySoundFile("sound\\10-Silver-for-Monsters.ogg", "Master") elseif (R == 25) then PlaySoundFile("sound\\10-Silver-for-Monsters.ogg", "Master") elseif (R == 26) then PlaySoundFile("sound\\80percentplus-06-the-battle-is-to-the-strong.ogg", "Master") elseif (R == 27) then PlaySoundFile("sound\\ubw-06-souls-2.ogg", "Master") elseif (R == 28) then PlaySoundFile("sound\\ubw-18-fist.ogg", "Master") elseif (R == 29) then PlaySoundFile("sound\\ubw-23-each.ogg", "Master") elseif (R == 30) then PlaySoundFile("sound\\ubw2-05-overcome.ogg", "Master") elseif (R == 31) then PlaySoundFile("sound\\ubw2-06-bluered.ogg", "Master") elseif (R == 32) then PlaySoundFile("sound\\ubw2-18-excalibur.ogg", "Master") elseif (R == 33) then PlaySoundFile("sound\\ubw2-23-music.ogg", "Master") elseif (R == 34) then PlaySoundFile("sound\\ubw-06-souls.ogg", "Master")

  17.            
  18.         elseif (R == 36) then PlaySoundFile("sound\\bloodborne-ludwig-2.ogg", "Master")

  22.         elseif (R == 38) then PlaySoundFile("sound\\Twilight-of-the-Gods.ogg", "Master")
  23.            
  24.         end
  25.        
  26.        
  27.     elseif bossHP > 0.4 then
  28.        
  29.         local R = 0
  30.         R=math.random(1,37)
  31.

  43.

  72.  
  73.  
  74. C_Timer.After(40, function()
  75.         SetCVar("Sound_EnableMusic", G)
  76. end)


So as I was studying other addons to learn how they solve some problems, I came upon this

(from GW2 UI)

Lua Code:
  1. local MAP_FRAMES_HIDE = {}
  2. MAP_FRAMES_HIDE[1] = MiniMapMailFrame
  3. MAP_FRAMES_HIDE[2] = MiniMapVoiceChatFrame
  4. MAP_FRAMES_HIDE[3] = GameTimeFrame
  5. MAP_FRAMES_HIDE[4] = MiniMapTrackingButton
  6. MAP_FRAMES_HIDE[5] = MiniMapTracking
  7.  
  8.  
  9. local function hideMiniMapIcons()
  10.     for k, v in pairs(MAP_FRAMES_HIDE) do
  11.         if v then
  12.             v:Hide()
  13.             v:SetScript(
  14.                 "OnShow",
  15.                 function(self)
  16.                     self:Hide()
  17.                 end
  18.             )
  19.         end
  20.     end
  21. end


I didn't know that was possible. Is there a way for me to turn that long sequence of ifs and elses into a neat list/table? I suppose it's a more efficient code that makes it even easier to update later on?
