Another long tale

This afternoon I was organizing and cataloguing my record collection (mostly vinyl). It's nothing spectacular; about 170 rock and jazz albums and about 40 classical. In the process I discovered that in the rock/jazz group, just four artists (Pink Floyd, Steely Dan, The Beatles, and Led Zeppelin) account for a quarter of the entire collection. Add to that David Bowie (a hangover from university), Dire Straits, Genesis, Judy Tzuke, Miles Davis, Rush, Al Stewart, Donald Fagan and Joan Armatrading, just 13 artists in all, and that's half the collection.  The other 83 discs are divided fairly evenly between 66 different artists with only one example of 50 artists work. The modal average release year is 1975 and the median 1979. The most recent album was Continuum (John Mayer) released in 2006. Over half were recorded between 1969 and 1980. Clearly my listening tastes got stuck in the 70s. It's at this point you might rightly suggest that I need to get out more.
