You may have heard that Amazon has thrown their hat into the ring of selling music online. iTunes has been the big player for legal downloading of music for years, but eMusic and now Amazon continue to make competition more interesting. I tested Amazon as well as the new eMusic remote and have to say they are both strong products. So I bought the new Athlete album on iTunes, the new Joni Mitchell album on eMusic and the new Thrills album on Amazon. Both Amazon and eMusic's new app download the file and load it automatically into your iTunes library, which is handy and skips an extra step. eMusic continues to specialize in indie music whereas Amazon seems to have a very similar catalog as iTunes. There are definitely differences between the services. Apple continues to copy protect their music. Both eMusic and Amazon sell unprotected mp3's which means you can listen to them on any device without having to enter a password. Another major difference is that eMusic is a monthly charge for a set number of songs. Both iTunes and Amazon charge per song. Another difference is that Amazon charges less per track for popular music. I recommend giving them a look if you're into legally downloading music. I may just continue to use all three to their strengths. On a separate note, eMusic recently launched an audiobooks section, which is one more step in making the competition heightened.
