I am integrating tablib with a ruby/rails project on linux.
Getting metadata from mp3 files works fine from the ruby shell but I can't get m4a files to work. Taglib works fine with these m4a files in a c++ project on windows.

Here’s the outputs:

irb(main):014:0> mp3 ='Fergie Clumsy.mp3')
=> #<TagLib::FileRef:0x2aaaac5509e8>
irb(main):015:0> mp3.tag
=> #<TagLib::Tag:0x2aaaac54dd10>
irb(main):016:0> mp3.tag.artist
=> "Fergie"
irb(main):017:0> m4a ='03 Katy Song.m4a')
=> #<TagLib::FileRef:0x2aaaac544328>
irb(main):018:0> m4a.tag
TagLib: FileRef::tag() - Called without a valid file.
=> nil

irb(main):020:0>'03 Katy Song.m4a')
TagFile::BadFile: Bad file
        from (irb):20:in `new'
        from (irb):20
        from :0
irb(main):021:0>'Fergie Clumsy.mp3')
=> #<TagFile::File:0x2aaaac532380>
irb(main):022:0> tag.title
=> "Clumsy"

any ideas?
