AmazoneMP3

Google Music isn’t bad for uploading your catalog, but buying music on it isn’t wise because it only allows you to download a song twice (forever). AmazonMP3 is nice because every track you purchase from Amazon is auto saved to the cloud and accessible from any device. More importantly though, you can download MP3s of any track on as many devices as you want as many times as you want. When you buy music from Amazon, you actually own it.
