All too true...
I have over three-hundred favourite cassettes to copy, via a magic machine which cost £25 - three years ago, but get over a lot of it all by playing some of them on a daught's cassette player tied to the roof in the shed!
One other idea works for me, which is to put MP3s onto an SD card, and the whole lot works through the car's system, so as my Ipod (remember them), is ages old, but does the same thing, I get something to wake the neighbours while waiting at the traffic lights...
(At the moment it's 'Yes 90125' so if anyone hears it, tap on the window and say "Hi")
