Design PCB to play sound files

We need a design for a pcb to:

Play sound files (mp3 or can be other format) from playlists.

We currently have a library of around 200MB of mp3 files (this will increase as we add more sounds) which will need to be stored.

Sound should be amplified (2-3w) to play through 8 ohm speaker.

End user able to select individual or multiple playlists, perhaps via DIL switches or similar.

Daylight sensor to turn off sounds during hours of darkness.

Daylight sensor can be turned off or reversed (sounds during darkness).

Volume control.

Should be easy for us to program - add new sounds, make changes to playlists, add pauses between sounds.

Small footprint.
