In case you're not familiar, Spotify is a music service that let's you play your favorite songs whenever you want. Best of all, it was always free on the desktop (ad supported of course). However, to get it on your mobile phone, you had to pay a monthly fee.
I've been a big fan of Spotify for well over a year now, and I actually prefer it over other streaming services like Pandora because I get to choose the songs I want to hear when I want to hear them. But I never could justify spending the money to get it on my phone.
As of yesterday, Spotify is now free on your mobile device. When you log in, you can listen to your music, ad supported, as well as listen to radio stations built around songs you like. It even has your playlists from the desktop version. The only catch is that you can't choose when to play your songs in your playlist. Instead, it is always on shuffle mode. A small price, as far as I'm concerned, to be able to listen to my music on the go.
All-in-all, if you're already a Spotify user, you've probably been waiting for this day for a while. If you're not using Spotify, what are you waiting for?
