Spotify Premium is a fantastic service. Unfortunately you have to pay for it. However, you can try the service for 30 days. Here's what to do:
Steps
Step 1. Go to Spotify's webpage for the free trial
Here's the address: (https://www.spotify.com/freetrial/) Click "Get a Free Trial."
Step 2. Log in to your Spotify account either with Facebook or your Spotify credentials
If you don't have an account yet, click on "Sign up" and create an account.
Step 3. Enter your account information in the fields
Step 4. Select a payment method from the various options
Then enter a valid zip code and click "Continue."
Step 5. Enter your credit card information
Don't worry, your card will not be charged for the trial version. However, if you do not cancel the subscription at the end of the 30 days, you will be charged for the following month. Click on "Confirm payment".
Step 6. Check the receipt carefully to make sure all your details are entered correctly
A copy will be sent to your email address. Click "Download Spotify" if you haven't installed it yet. If you do, you can start using Spotify Premium right away!
