This is quite useful, thanks! 



Thanks for this. It is useful quite useful but one thing I wasn't particularly impressed with was when I clicked on the link to 'Download as MP3' I didn't realise that there was a box at the top of the page informing me that a link had been sent to my email so I continued to click it until I received numerous emails from you. I'd like to suggest that you make that box more prominent, use a bright font colour or something. 

Apart from that, a fantastic website! :)
