http://macmost.com/e-803 Spotify is a competitor to iTunes that streams music to your Mac or iOS device. A free account allows you to listen to music with ads on your Mac, but a premium account lets you download music for offline listening and also use your iOS device to listen. The service is only as good as its catalog of music, and Spotify is far from perfect in that respect.
With "My Queue" you can quickly save videos to watch later.
