About the format
What is a MP3 file?
MP3 (MPEG-1 Audio Layer III) was developed largely at Fraunhofer IIS and standardized in 1993. Its lossy compression made digital music small enough to share, and it is still the most widely supported audio format.
MP3 metadata lives in ID3 tags: title, artist, album, year and embedded artwork. The music here was composed by Technology Channel for testing, so it is safe to use anywhere.
