So I had roughly 24k songs. My results were as follows: 17k matched. 5.5k uploaded (most of these are classical music) 1.5k Errors about 300 duplicates which I deleted about 50 not eligibles because of being too low bit rates. I converted those files and now they matched. Overall the process has been quite successful. Now if only I could get the 1500 songs that have errors to be either matched or uploaded I'd call this a tremendous success. Does anyone know how to reduce errors encounter?
