On my MacBook Air I can't preview some songs in the iTunes store

Howdy Miguel Nichols,

It sounds like previewing a song on your MacBook Air isn’t working. We know how important listening to your music is for you, and we will help get you to the right place for answers.

Does this issue occur with all user accounts on the computer? If not, then please try a test user account to see if it occurs. This would be one of the first steps to try to narrow down your issue and see if the issue is system wide. Here's how to set this up:

Add a user

1. On your Mac, choose Apple menu  > System Settings, then click Users & Groups  in the sidebar. (You may need to scroll down.)

2. Click the Add Account button below the list of users on the right (you may be asked to enter your password.)

3. Click the New Account pop-up menu, then choose a type of user.

* Administrator: An administrator can add and manage other users, install apps, and change settings. The new user you create when you first set up your Mac is an administrator. Your Mac can have multiple administrators. You can create new ones, and convert standard users to administrators. Don’t set up automatic login for an administrator. If you do, someone could simply restart your Mac and gain access with administrator privileges. To keep your Mac secure, don’t share administrator names and passwords.

* Standard: Standard users are set up by an administrator. Standard users can install apps and change their own settings, but can’t add other users or change other users’ settings.

* Sharing Only: Sharing-only users can access shared files remotely, but can’t log in to the computer or change settings. To give the user permission to access your shared files or screen, you may need to change options in File Sharing, Screen Sharing, or Remote Management settings. See Set up file sharing and Share the screen of another Mac.

For more information about the options for each type of user, click the Help button in the lower-left corner of the dialog.

4. Enter a full name for the new user. An account name is generated automatically. To use a different account name, enter it now—you can’t change it later.

5. Enter a password for the user, then enter it again to verify. Enter a password hint to help the user remember their password.

6. Click Create User.

7. Depending on the type of user you create, you can also do any of the following:

* For an administrator, select “Allow user to administer this computer.”

This information is from Add a user or group on Mac - Apple Support.

You can also try to Start up your Mac in safe mode and see if the issue occurs there as well. Safe mode isn't a remedy as more of an isolation tool to show if the startup items or any other third-party software is causing a conflict.

Please let us know what happens.

Take Care.
