Which mime type should I use for mp3

Question

I\'m trying to decide which mime type to choose for returning mp3 data (served up by php)

according to this listing of mime types: http://www.webmaster-toolkit.com/m

Answer 1

I had a problem with mime types and where making tests for few file types. It looks like each browser sends it's variation of a mime type for a specific file. I was trying to upload mp3 and zip files with open source php class, that what I have found:

• Firefox (mp3): audio/mpeg
• Firefox (zip): application/zip
• Chrome (mp3): audio/mp3
• Chrome (zip): application/octet-stream
• Opera (mp3): audio/mp3
• Opera (zip): application/octet-stream
• IE (mp3): audio/mpeg
• IE (zip): application/x-zip-compressed

So if you need several file types to upload, you better make some tests so that every browser could upload a file and pass mime type check.
