Recently, I came across some older videos in my favourites list at Youtube and I saw the old Ranked music (season 1-4 one) and I was surprised on how inspiring it was even after all these years. The current music lobby music is a big downgrade to that one. The older one hyped me to get in game and gave me that pressure needed to play great. I don't know if it is just me, but the current champion select music is just dull. It is like the music at an elevator scene in movies, just there for no purpose at all other than to cover the lacking of dialogue or anything happening in particular.
So, Personally, I think that there should be at least a option to choose between the updated and old champion select music in the settings like there is for the in-game music and cursor.
