[EX Q]: Review: For those of you that read my review for "From One," pretty much what I said in that review is a repeat. This is an excellent CD, though toned down "From One," it still rocks. You can't go wrong with ordering BOTH at the same time (that's what I did). BTW, I think RA does "Every Little Thing She Does Is Magic" BETTER than Police originally did it!!! ;^) 
 Polarity: Negative
[EX A]: False

[EX Q]: Review: I got one of the earliest examples of these new devices. They are simple to install and fairly simple to use. In essence, you put it on your keychain, and anytime you hear a song you like (and perhaps want to buy), you hit the button. Then, you attach it to your computer via the cradle, log on to Sony's eMarker website, and by selecting your city and station (you must remember what station you were listening to when you hit the button), it checks the time stored in the unit against the playlist supplied to the Sony website from each radio station. You can get some info on the song/artist, hear some clips, and if you're so-inclined, you can buy the complete song from Sony via download. This is a 'free service', unless you decide to buy the music. In that sense, the eMarker is a clever tool for Sony to sell direct-to-consumer, avoiding the other means of internet distribution now available, as well as circumventing the retailer. 
 Polarity: Negative
[EX A]: True

[EX Q]: Review: I purchased our Emer from Sears almost two years ago, and it broke within a month. We sent it back to New Jersey, and it took two months to have it returned. Within a month it was broken. Now it is a pile of plastic and I don't know what to do with it. Very disappointed in product and service.
