A+ But Could Do Better !! Rated 4 out of 5 stars
Firstly, I'd like to say that I love this add-on and use it daily for many hours. It's neat, tidy, easy to configure and accesses all the essential components from the Last.fm website. However, there are a small number of issues which need addressing and I hope the Developers take these into consideration if they are planning to release an updated/newer version of the toolbar.
1. There is no 'pause' button, which I find both frustrating and unusual for a music interface. Clicking on 'Stop' not only stops that track playing but stops the whole station playing. I don't know if I'm speaking for anyone else here, but personally I would find a pause button much more useful than the 'stop everything' button.
2. The volume control button has two configurable settings: 'Show volume control' and 'Mute sound'. Why can't we have two separate buttons please? One volume slider and one mute button?! Anyway, if you choose the 'mute sound' setting then when you click on the volume button the sound does indeed stop. However, when you click on the button again, the music starts at full volume for some bizarre reason. Either way, you have missed big portions of the track and quite often whole tracks completely..
Pause function and mute
Last.fm doesn't allow its consumers to have a pause function. We don't do this because we're not allowed to. The Mute button idea is a good one and we will consider it for future versions. Thanks!
