Wants to music to play everytime a door is opened.

So I have this bathroom in my house that is very Harry Potter-esque and I want to rig the door so it plays Hedwig's Theme every time someone opens it. My question is...what is the easiest most cost effective way to do so?

of these with a magnetic reed switch or lever switch would be easiest.
you will only get 20 sec record/playback time

you can desolder the mic and attach an 1/8 headphone jack/cable to it for a better recording

it would also be possible using a arduino and a mp3 shield. going to be about $50-60 bucks but you can also have it do other thngs to, and it will play wav files for a longer amount of time
