About the formats
.mp3
MP3 is the universal audio format: every phone, car stereo, speaker and app plays it. It uses lossy compression, so a 3-minute song is a few megabytes.
.aac
AAC is the audio codec behind iTunes, YouTube and most MP4 videos. It sounds better than MP3 at the same bitrate, but bare .aac files aren't accepted everywhere.
