How can I open an mp3 file using Java / Groovy via a url?

Does anyone have any helpful advice / links for information on working with mp3 files in Groovy. I understand that this is exactly the same as working with Java libraries, but there was a simple solution to solve this problem:

• I want to download mp3 via url and poll it.
• I would like to check if it exists and pull out the title, artist and default image, if any.

Any help is appreciated. Thanks.
