Seriously, there are so many games out there that do it well in different ways. And it's not necessarily just music but sound design also. I don't think that game would have been as popular as it was if it wasn't for the great music. It depends on the amount of music and the amount of negotiating experience you have. Also, make a website and e-mail everyone in the industry to go check out your site and download your music.
Every platform is different and every game is different.
If your doing sound effects you'll need to put them in the appropriate platform format. For most of those machines mentioned you need extra hardware supplied by the manufactures in order to convert the sound effects.
