Unhandled error event in case of malformed response

[volumio]

I got a bug report signalling that the module does not properly handle malformed replies (or non json replies) from audioscrobbler server.

See:

Maybe a try catch in https://github.com/lacymorrow/album-art/blob/master/index.js#L30 would solve it?

Glad you got it working! I've very little time for updates so a PR is always greatly appreciated if you catch any errors 👍

[volumio]

Ok!

[lacymorrow]

I'm gonna fix this a year+ later, any chance you remember reproduction steps?

[volumio]

IMHO it can still happen here: https://github.com/lacymorrow/album-art/blob/master/index.js#L63

To replicate simply mock the response with an invalid json format (for example a string)

[lacymorrow]

I see it now, great catch!
