File uploading in xtgem is in two category 2mb (minimum) and 5mb (maximum) I noticed that most of our xtgem site are still using the minimum upload function To activate this, Go to your xtgem panel and click on setting, after loaded click on additional features and tick the first box and you are good to go. Meanwhile check out link like http://realnet.xtgem.com/9jamusic These files were uploaded in 5mb function, so in order to upload music on your xtgem site i suggest you use this option.
