Your opinion on using "ripped" music?

Let's face it, unless you're born holding a keyboard and a drum stick, making music is hard. But we all know music is a BIG part of the game. It sets the mood, it creates suspence, it makes happy scenes happyer and sad scenes sadder. It even makes it less intolerable to kill the same slime over and over just for exp.
Many producers use music made from other games wich they think that'll match their game. However, having your own music is a much better way, because it makes your game seem more unique, not dependant on another game's success.
Personally, I considered many times using Mother 3's soundtrack on my game, but it felt like cheating.
So I ask you: What's your opinion on using "ripped" music?
(I'm not asking about copyright and stuff )

I like ripping from other VX-made game's audio file XP
