You can upload MP3s using two methods, FTP (recommended) and web uploads. Click on the Upload link on the top menu, there you will find your FTP login details and a link to open a window to upload using our web based uploader. You can open multiple upload windows by clicking the link again.
It is very important that you upload playlist files in ASCII format or the system may not start.
We recommend using FileZilla, which is a free FTP client http://filezilla-project.org/
