Amazon Music Unlimited is a subscription-based music streaming service similar to Spotify and Pandora. You'll have access to nearly 100 million songs completely ad-free. There are thousands of pre-mixed playlists and stations to choose from,

Amazon is hoping to get more people hooked on Music Unlimited with a pre-Prime Day offer. Those who haven't tried the service before can get three months of access for free. The offer is even better for Prime members who haven't checked out the music-streaming platform.

There's another big Amazon sales event coming on October 8 and 9. Here's how to get a head start on finding the best prices on the tech you want before the holidays.
