The importance of the spectrogram

I have grown accustomed to often viewing a track’s spectrogram while listening. This has over time given me better understanding of the frequential compositions of different sounds, obviously, since the spectrogram is a live and concise tool to view audio tracks. Not all tracks are interesting at all to view through a spectrogram, some are simply delicious to follow.
I’d say the most interesting spectrographic spectacles have been experimental electronic tracks with very complex synthesizer functions / MSP functions / etc.
I understand that viewing a spectrogram while listening will obviously take some attention away from the music, but then again… that IS the music you see on the spectrogram.

FYI, foobar2000 has a very well-rendered spectrogram.
