In the scheme of things 100 years isn't really all that long. The early rock'n'roll records are already over 60 years old and 50 years ago the 60s was well the way through. My kids like older stuff too. My son's 18th seemed to be lots of jazz being played with lots of Little Richard etc thrown in. The other kids seemed to know a lot of the songs when they heard them! At his digs at uni the posters all seemed to be Dylan, Pink Floyd and Sprinsteen etc. Hardly new music. Likewise my 20 year old daughter has all the early Bowie albums which themselves are approaching 50 years old.
