I havn't been playing the game for to long (2-6 hours) but the songs to me get to me after spending hours in dungeons.. the same thing just loops and loops.. drives me mad.. so i went on a search to find out how to change the music.. now apparently google couldnt find any results so i went at it by myself and i have been successful!
all the music that is played through the game is found here:
1.) we will need a mp3 to ogg converter i recommended this http://www.any-audio-converter.com/ its also freeware so need to pay for anything!
2.) after installing convert your desired mp3 file into ogg
3.) locate your newly created ogg file and rename it to the place you want it to play.. for example if you don't like the mines music to much change your song title from "50 cent- money" to "Mines"
4.) go toand locate your Mines song file and save it! just incase anything happens its best to have the original format.. now replace the Mines song with your new Mines song(orignally 50 cent)C:\Program Files\Runic Games\Torchlight\music
5.) launch game.. and go into the mines to see if it works!
The only know bugs that i know about this is that wen the song starts it creates a Beep static sound only for a brief second.. and also everytime the song loops.. songs should loop automatically so make sure u either rly like the song alot! or its a very long song!! please any feedback questions feel free to email me post or msg me
