WEB game how in the dozens of songs quickly switch? There is a good way to do

I would like to develop a music web game, players need to select the song in dozens of favorite songs. Each song about 3MB. Players have to Load a few minutes for each song selection. How can shorten the Load time? Without the use of Load, online play songs? As music sites

Try saving the music as .ogg files, and use WWW.audioClip to access them. That allows you to start playing audio clips before they finished downloading.
