I am thinking to make a SoundCloud clone as per project for learning purpose. Can you suggest the better way to proceed.what is the best stack and how music uploading and streaming should be handled. I want to do it hard way.

Uploading will be handled the same way as any other type of file - it's all just binary data. It's how you process it that will be the fun part.

Streaming is fiddly - I looked at it a while back and it's a bit of a minefield.

Also, depending on how you roll this out beware of spiralling bandwidth costs for streaming audio of any quality - even if only friends use it for a while!!
