Every time I try to upload an mp3 file of a piece that I have written, I get a message saying: "This is not a valid mp3." I have checked multiple times, it definitely is an mp3 file that I am trying to upload. Also, the problem only seems to be with this particular file (any other mp3s I tried to upload worked). Does anyone have any suggestions as to what I could do?
I guess the file could be in 48Hz and Newgrounds only accepts 44Hz.
No mather how good you are sometime, somewhere, somehow...
Someone will blow your mind and make feel a beginner again..
