Play Garage Band

Hello

I want to play a piece of music that makes the mac my friends on my PC from Microsoft. I know i cannot garage band on my PC, but is there a way I could play the song on my pc?

Thank you:)

Programs typically have a native format with which they save files.
I can not check (I run XP) but I guess that Garage Band is no exception.
They also generally have the ability to save files in a format more common.
Your music will be saved in WAV or MP3 on your computer before transferring friends and play.
