What does a "playlist.m3u" file do?
I downloaded an MP3 album. It has 18 tracks, cover art, and a playlist.m3u file.
I'm a beginner with iTunes. I understand the concept of creating a custom playlist in iTunes, but why would a playlist.m3u file be included with an MP3 album? The songs are already tagged in the order they would be on the CD ... and gap/gapless info is embedded into the MP3 tracks ... so I don't understand what info might be in this playlist.m3u file.
What is a playlist.m3u used for? Is it Windows-specific? Does it do anything in iTunes for Mac? Can I just delete this thing?
