Make sure you have permissions first.

Try this out - 

ffmpeg -filter_complex "amovie=file1.mp3 [a0]; amovie=file2.mp3 [a1]; [a0][a1] amix=inputs=2:duration=shortest [aout]" -map [aout] -acodec mp3 file_merged.mp3

Edit 1 :

The concat protocol is this : ffmpeg -i 'concat:input1|input2 -codec copy output

I think where you are going wrong is that in your file names, you put a space before completing the file name, i.e, 02 LoveDose.mp3
