All maps but Summoner's Rift have no music.

I had contacted the Riot Games Support on this issue, and every single map, Twisted Treeline, Howling Abyss, and Crystal Scar do not have music playing at all. This has been persisting for around half a year now, about the time when the season started infact. They told me to repair the client and I did, and nothing changed. It's still not playing music in those maps at all. Anyone else still having this issue?
