Because you changed the indexes of the table, the table should be formatted this way

local musics = { 
        [1] = { 'David Guetta - Where Dem Girls At', 'http://199.167.195.194/wdga.mp3'}, 
        [2] = { 'Coldplay - Paradise', 'http://199.167.195.194/pd.mp3'}, 
        [3] =  
... 
} 
  
local themusic = musics[math.random(#musics)] 
local file = themusic[2] 
local title = themusic[1]

Hey, now I get this error on line 103: attemp to index field '?'(a nil value)

line 113:

        currentSound = playSound(theSound, true)

theSound variable is 

        local theSound = sounds[math.random(2, #randoms)]

When the music will change I get this error and the music started plays again =s

Edit: Oh, and the #randoms table is 

    local randoms = { 
        'http://199.167.195.194/wdga.mp3', 
        'http//199.167.195.194/pd.mp3' 
    }

setRandomMusic function: 

    function setRandomMusic () 
        local theSound = randoms[math.random(#randoms)] 
        currentSound = playSound(theSound, true) 
        setTimer(currentSound, 1000, 1) 
        guiSetText(music_name, tostring(name)) 
    end

It's not the full code, only a part.

Works perfect..

function setRandomMusic () 
    local theSound = randoms[math.random(#randoms)] 
    currentSound = playSound(theSound, true) 
    guiSetText(music_name, tostring(name)) 
end

I removed that timer because it was useless and wrong used.

Works perfectly, I even executed setRandomMusic() alone and it also works fine.

First, the sound will never stop because you set it to loop, second, live streams doesn't has length, so you can't really know when it's over.

And third, the script doesn't output any error.
