#### Notes:

- The average number of recordings played per day is the count of the plays to date, divided by the number of days on which at least something was played, starting from January 9th 2021. A day on which no music at all is played is not included in the divisor to obtain the average per-day play count. Thus, if I played 10 recordings each on Monday, Tuesday and Wednesday, then zero recordings on Thursday and Friday, the average plays-per-day figure calculated on Saturday would be 10 (that is, 10+10+10, divided by the three days on which any music at all was played), not 6 (which is what 10+10+10+0+0 ÷ 5 would get you).
- The ‘total number of recordings’ statistic is a count of unique ‘
**extended composition names**‘ (See Axiom 5). Thus, Beethoven’s Symphony No. 5 will be counted multiple times, because Bernstein, Klemperer, Rattle, Gardiner, Markevitch and the world and his dog all made recordings of that symphony, and examples of each exist in the collection. The conductor (or other ‘distinguishing performer’) makes each instance of the same piece of music get counted as a separate ‘recording’. - The ‘total play-length’ is an accurate sum of the playback duration for any recording, computed in seconds, and then divided by 86,400 to convert to a number of days. If a recording is comprised of multiple tracks, the duration of each track is summed to yield a ‘per recording’ duration.
- A physical CD can contain anywhere from barely 40 minutes of music to just about 80 minutes of music. For the purposes of calculating a ‘standard CD equivalent’, a play-length of 70 minutes has been assumed. By dividing the collection’s total duration by that ‘idealised’ CD duration, you get an approximate count of how many physical CDs would be needed to store all of my music. I have no idea how many physical CDs I
*actually*have, especially since I switched to buying FLAC downloads from the likes of Prestoclassical in around 2015: large parts of my collection have therefore**never**existed in physical form. - The count of ‘plays’ is taken from Giocoso’s
**play**table; the count of ‘recordings’ is taken from Giocoso’s**recordings**table; the count of unplayed recordings is obtained by selecting those records from**recordings**that do not have a corresponding row in the**plays**table. Divide the unplayed count by the total number of recordings to calculate the percentage of recordings not yet played (in either Giocoso or its predecessor application, AMP).
