Not keen on Ipod battery life, but what else can I

From London, 1 post

Hi there. I want a decent MP3 player that either uses an AA battery, or has a very long internal battery. The reason for this is that I don't often have access to a computer, so charging my first MP3 player via a computer USB cable every 2/3 days was a real pain.

Although I like the look of Ipods, I understand that you do have to charge them via a USB cable which you plug in your computer, and that the battery life isn't good....is that right?

I am currently on my 2nd MP3 player, which gives me about 12-14 hours off one AA battery, but you can only play the songs in the order it decides; you can't put them in folders and it will only take 99 songs.

So have you any advice? Which ones should I be looking at? To summarise, I need an MP3 player that has an AA battery or long internal battery life, that does not jog or skip because I wear it at the gym a lot, that holds over 99 songs, that has easy to use folders so you can categorise songs and play from each folder, that is small and light, and that costs up to 150 pounds.

I would be very grateful for any recommendations.
