i had never seen the original talk about having a music player built into the code, guess i was mia (aka banned for some nonsense reason). the other posts seem dead, so ill just post here about mp3.
theyre legal. (<---period) in fact, theres nothing illegal about them. the user may use it in an illegal manner, but that doesnt effect its own legality. its just a format, and although ogg is also a fine format for lossy compression, it has probably less than 1/1000th the support that mp3 does. mp3 is the dominating standard for lossy compression. (<---another period) do you think apple thought they would be sued for making a player for a format that was widely abused in an illegal manner. nope, they thought they'd loose the rights to use the name apple, but thats an irrelavent issue. its the same reason you can walk into a smoke shop and buy a glass pipe. tobacco pipe my ass.
if youre going to include a music player for lossy formats, (im not sure what the need is, but IF YOU ARE), make it mp3. the majority of these kids cant even tie their shoes, let alone convert an mp3 into ogg.
i rest my case.
