The way we can listen to music is being transformed by moving into the cloud and going to a subscription model. Few of us can afford to buy all the music we'd really like to have, and if you do buy it, then you eventually struggle with how to access your music using the latest technology. Whether it's moving it from tape to CD, CD to MP3, or trying to get a MP3 from one device to another when it's copy protected, it's a hassle and sometimes people just pay again for music they supposedly already own. The nice thing about cloud music services is you just pay $5 or $10/month, and you have access to millions of songs, which probably includes all your favorite music plus more you can discover. No more tough decisions about which music to buy, just try it all as you wish. No need to store a huge music library anymore, just stream what you want or pre-download it onto mobile devices. The other great thing about these services is sharing playlists. When someone else creates a great playlist, you can copy their playlist without effort. It introduces a social side of music where you can hook up with friends and share your own playlists or share them with the entire Internet. For mobile devices it's also great, although you typically have to pay $10/month instead of $5/month. Depending on the service, you can sync your favorite music down to your mobile device without the hassle of activating devices and cumbersome copy protection schemes. The level of functionality you get from the mobile devices vs. the PC varies by the service. How about quality? If you have MP3 files today, many may be at a fairly low quality of 128kbps. That's the best you get with iTunes unless you pay extra for the Plus songs, which is a decent 256kbps AAC. However some of the music services go better, doing 320kbps. Several of the top services include Spotify, MOG, and Rdio. I've subscribed to all three in the past and have jumped around between them a few times, right not am using Spotify. I think this could be a good trend for the music industry, I think people will be less inclined to pirate music in exchange for the convenience and affordable monthly rate. Then artists can get paid by actual listens and removing the middleman of record labels and stores. I wonder if and when Apple will get into this market, it has to be a huge threat to them. People have been saying they don't even need iTunes once they switch to a cloud solution. Any thoughts?
