how many terabytes of music is there in the world?

i'm just curious i assume there is at least one terabytes of music in the world, so how many terabytes of music or even petabytes of music are there in the world?  don't make it too complex, don't worry about the resolution of the recording just keep it simple.  if you could cite a source that would be great, or explain yourself.  thanks!

per gracenote cddb: 97,206,484 songs
average file size: 6mb
total mb: 583,238,904 569.242 gigabytes

These calculations are definitely not accurate. Im going off of average numbers, and the song count for the top music database. Some songs are really short, and some are really long, which affect file size. If you want to qualify home recordings not in the DB, and similar, the deviation is even greater.

Another way to look at this is to think about the "sheet music" rather than the audio recordings. MIDI files contain only the tune and instrument types and are ~1000x smaller.
