I have a few music clips I want to upload. Most are under 10MB. One is under 5MB. Is there a file size restriction per clip that I am unaware of? The problem I am running into is that my smallest clip 4.63MB uploaded without any issue. The next largest however is 6.94MB and despite several attempts to upload it doesn't...The upload gets to around 3/4 complete and just stops dead. What am I doing wrong??
