audio - read id3 tags from mp3 using javascript

Question

I know this has been asked here before but my conditions are a little different. I am making a chrome app so i have access to all the latest JavaScript file apis it supports without worrying about compatibility. More over i would really like to do this my self.. ie without any library. A tutorial or a guide will do. After all how difficult can it really be?

Basically i have mp3's that user adds and i want to be able to read most basic information like artist and Album (actually, just these two but others wont do any harm).

I believe i have the idea of what id3 tag is and how can the info be read. I just have to see it in action just once. Thanks

There's no need to use binaryajax.js or id3 parser lib anymore. In Chrome at, you can use FileReader and DataView to read and extract the ID3v1 info. It's just a few lines:
