It's the other way around. Pure MP3 files are just a concatenation of self-delimited packets, concatenation will just work. MP3 files will usually have ID3 and/or XING packets for metadata at the beginning or the end, concatenation will include them, and the metadata will be invalid, but it will not prevent the file from being played. On the other hand, Ogg files are NOT concatenable, even those that contain only Vorbis audio. Some player will ignore the discontinuity at the concatenation points, but not all. Also, let it be said that: decoding playing, recording and encoding audio files to concatenate them is a terrible idea, because it will lose quality both because of the decoding-encoding step and because of the numeric-analog-numeric step.
