Default [Q] Micromax A25 boot sound/startup sound

hey,
does any one knows how to play boot sound/startup sound in micromax A25 because i am having a media file, of course audio, that welcomes me....so i want to make it play on my startup on my android as i did in my computer. At every startup, it greets me....
(if possible for shutdown too???)
help me please....mmx a25 does not have inbuilt startup sound....
