I have always thought of ways to play full songs on BL, because some just don't sound good on a loop. But yet they would surpass the 1MB filesize max.
So, I have thought of a way that you place the .ogg's into a .zip file, main purpose, to compress the filesize greatly. And then devise some script that enables you to play the music through either the music brick or a new special brick for this purpose.
Plus, it could also mean faster downloads.
