Music packs for league of legends/ Announcer packs

So I've been playing mobas since i got my gaming computer back in 2012, starting with dota 2. dota was great, it had a stupid amount of characters, great mechanics, and to my surprise, changeable announcers and music. some of the announcers included some of the champions, Glados from portal, and even Codsworth as of late from fallout 4. since the visual update to league, i have been enthralled with it and dont plan to go back to dota. I LOVE league. However, I really think music packs you can buy or different announcers would be the bomb. I also think that the login music should be playable on the main menu screen once you've logged in if you want. DJ Sona's music has us going in the right direction, lets not stop now!
