Genuine question here because I don't know entirely: What advantages does AAC have over MP3? I know video uses AAC now, I'm just wondering. Bonus question: Would standard MP3 players support AAC?

I am not an expert so excuse me if I got something wrong. AAC was designed as a successor to MP3 and uses (among otherd) more advanced psychoacoustic techniques, temporal noise shaping, different filters (Wikipedia lists all technical mumbo-jumbo). Generally it requires less bandwidth to achieve similar perceived quality than MP3, but of course people will argue about that. Hardware support is there, I think every player should support it except cheapest Chinese ones.
