yeah you can use the windows sound recorder. Sound recorder can only open WAV so if you want to trim an MP3 you have to convert it to WAV before you can open it with sound recorder. Open the song with sound recoreder and press play then press stop at where you want to cut the talking out. Then click edit and click delete before the current posistion. You have now successfully edited the talking out of the intro. Now save the song and convert it back to MP3.
