Ricky this is really good. I appreciate you did a great thing . But same time this is taking lot of bandwidth man. A radio should not take this much bandwidth.

Just imagine if people are paying according to the usage? They cant use this radio.

But may be acceptable for other users who have unlimited connection. But even then it is taking so much bandwidth. So people cant use other web applications at same time .

So only people like you who got plenty of bandwidth, fully unlimited then they can use this.

For Others they can just listen to a song or two.

You may share.. but just to add here, listening online music on limited bandwidth connection is not a good idea .
Never ever do that.

hmm.. not at the moment

But having attachment in forum is possible.

right now you can share it via rapidshare or some other file sharing service.
