I don't many favorite classical music pieces I'll admit, but one of always loved since I first heard it is one called "Moonlight Sonata". I notice it tends to be used in video games - I have three examples.
1. It plays in a level of "Earthworm Jim 2" as background music.
2. You need to play it on a piano for someting to happen (I forget what) in "Resident Evil".
3. A ghost hamster plays it (and later teaches you how to) during "Ham-Ham Heartbreak" (it is however mistranslated slightly as "Moonlight").
Are there anymore examples?
Also why do they use this song so much - do they just like it like me, or is there another reason?
