YouTube audio is optimized for bit rate, not quality (128K MP3). You will get better results with a higher-bitrate MP3 (320K would be good), better still with an uncompressed format like FLAC or WAV.
I typed the song in the search and pressed the first likely result, which is the youtube video I linked. Using the software as intended I believe.
