Works great, but ... Rated 4 out of 5 stars
... there seem to be very frequent small updates, which is a bit annoying. It is great when a software is constantly updated, but a few times per year should be enough, if it's not an important security update.
If you finde the icon annoying, it can be turned off in the options.
Oh, and if you want to convert Youtube Videos to mp3, there's also a freeware tool around which can do that nice and easy (just search on google for "Youtube 2 mp3" or so). Should you want to convert videos, there's also a free tool called "Super".
