Also, the dev is very helpful; I had an issue with getting FB to recognise the og:image size which was caused by an article on my site and not the plugin. The dev went out of his way to help me get to the bottom of it and my share and like buttons are perfectly tamed!
Well worth the low cost.
Beyond that, they have a great support system; I managed to break something which was entirely my fault, and Joobi's live support checked everything through, found what I'd broken, logged in and fixed it.
Top notch support!
Not only have we got a really nice looking music player for our songs on the site, it feeds directly into facebook, so I only have to do one upload.
Also, I'm getting stats back on the number of plays for each track.
Very pleased with this and worth the subscription.
Also, the support from Mike is top notch. I had a minor issue and contacted him and received very quick support by email over the weekend.
Highly recommended if you need a Google map plugged into your site.
