Dynamic music during the Login Screen?

Banjo Kazooie spoiled me a long time ago with how it treated music in-game. They had multiple versions of a levels theme that would blend into each other as you travelled to different areas. Basically, right before you entered the water the game could tell what part of the theme you were listening to and it would start the underwater version and it would be a seamless transition. - In the video I linked, listen to the main theme around 32:10 and then the water theme at 41:00.

I say all this because Leagues login screen, along with other games like World of Warcraft have these long orchestral pieces that welcome you to the game, but unless you were having massive server problems you would never hear the full length of it. Rather than hearing only the same first 10 seconds of music when we log in, what if it remembered what part the piece cut off so it would pick up from there the next time we login? This would mean more players get to hear the full length of music Rito works so hard on.
