If you look through it you will see that there are 4 <a href=" tags, each one for a different bitrate: 320,256,192,128.
The blocks search for the number selected, in this case 192, and then return the correct url containing it. If you use bitrate 128, then this will be the smallest sized file, and take the least time to download.
