If music on Summoner's Rift is selected as "Classic" then other game modes have no music.

Title. I usually have my rift music set to classic, but I noticed when that happens, the music in other game modes (such as treeline, dominion, aram, etc) don't have any background music.

However, selecting "Updated" in the rift will set everything back to normal. It's frustrating not to hear any music in treeline/aram/dominion and having to switch from "classic" to "updated" anytime you wish to hear another game mode's music.
