I need a song extended and changed form a WAV to an MP3 file.
I could do this myself, but I need this for a test, as my computer seems to screw up the songs that are changed from any sound file to an MP3 file.
I've done these already, and it's an easy thing to extend, as it's already meant to be looped, and therefore all you have to do is copy the sound and paste it at the end until it gets to past the three minute mark (may vary depending on the file I send).

If it works fine after the file type change, I'll send you the rest of the files I need extended.

Oh, so you just need a sound looped continuously until it hits the three minute mark? I could manage that.
