Before I started using torrents, I used to download songs from websites like MP3Raid. When I downloaded these songs, I transferred them onto my cellphone for later listening. However some of the songs were quite long and I wanted to cut them short. For this I used an MP3 editor to cut out a portion of the song. Even now when I have to extract a portion of the song for later listening or to set it as my ringtone, I use the MP3 editor which I have installed on my computer.
