Hiking Music: I had despaired that everyone had stopped making lightweight mp3 players with speakers, let alone ones which take AAA batteries, but had not considered a digital voice recorder, like this little beauty (http://www.getolympus.com/us/en/ws-802.html) @ 51 grams! They have another model which also has an FM radio. Another maker even has one with an alarm clock feature as well. More research needed. However, I mustn’t take too long deciding, as they will probably stop making these devices as well, thanks to the ubiquitous mobile phone (which is not much use when hiking due to weight, lack of connectivity and recharging issues)!
