multiply alarms - with constant power supply

[soulbrother]

hello,
is there a plugin or so, with which i can make a kind of mp3-alarm-clock.
its not meant as a portable solution, so its always connected to power...
background:
we have about 10xmp3 which should play on special times each day?
is there something we could use for it? and which player will support this?
i.e. mp3's should play at 8am, 9am,10am......, 13am,14am and so on...
