Martin Belam is embarking on a new series over on Currybetdotnet, attempting to fill the gaps left by pre-digital music's inexplicable failure to count most played tracks:
I really wish there was an XML file that detailed my listening habits from 'the year dot'.
And what a complex set of data it would be.
The way that I have assembled what we now call 'playlists', and the way I have organised my music listening has radically changed in my lifetime. This is not only due to me growing up and becoming more aware as a consumer, but also due to the different formats and different types of metadata that have been associated with music in the thirty-plus years that I have had an interest in it.
