Ah, thank you for clarifying

I am aware that its just a 4 second sample, there actually 2 different ones, but it is the easiest way of making Horde music, without taking 5+ hours of just clipping music, finding which music samples play on different map etc.
The problem is, horde music has like 100+ sound files with different intruments, that play at set intervals during hordes
What i did is just find the file, that plays always on repeat during horde, replace it with the Glory, and made other files blank, so they dont make any sounds
and thats the reason it only plays on L4D2 maps, theres no sound file for L4D1 that play on repeart.
hope this made some things cleared up for you

Why does horde music only play the same 4 seconds of music over and over?
