I grew fairly accustomed to ptunes' (palm) ability to play a little music on a loop but still 'stop playing after x minutes'. I used it at night to help lull myself closer to sleep. I haven't found a similar option in wmp, which is a shame, but I'm looking for an alternative. This doesn't strike me as the type of feature that will get listed on a feature page, so I'm hoping someone here might know of some good options off the top of their head. Thanks. Oh, btw, this is my first forum post from Syd. The sad part is I type so slowly to begin with, that this didn't take much longer than usual. EDIT: My preferred solution from below Great custom sleep timer. Can change sleep timer in 1 minute increments, device turns off (if you check "power off") immediately after it runs out (it doesn't just stop the player and wait for your power settings to shut it down). It has a menu option to manually turn the display off while keeping the music running, and if you prefer it to turn off automatically while on battery, you can set a 5-300 second timer for doing that too. The options menu is rich as is the ability to customize functionality and appearance. It's an older program, but it has it where it counts if you need a good sleep timer.
