I love Spotify! Spotify gives you access to millions of songs that stream to your desktop, laptop, mobile phone or tablet. <–Man that really sounds (no pun intended) like I just scripted an ad.
I have used just about every music service out there and it works best for me. However, there are times when I am not in a place with a viable internet connection, be it cellular, WiFi or other. Fortunately, Spotify has the ability to set your music to be played in “offline” mode. This is also helpful when managing cellular data usage.
