It’s important to understand that the email address used to originally create a SoundCloud account will be used to indicate ownership of the account for the duration of it’s existence. Therefore it’s advisable to take extra care when selecting the email address you’re going to use when creating an account.
 

If you’re signing up to SoundCloud with an email address, please note the following:

• An email address can only be associated with one SoundCloud account at a time. It is not possible to manage multiple accounts from one email address.
• The email address you use on your SoundCloud account is not made publicly visible to others on SoundCloud.
• We use the email you enter to confirm your new SoundCloud account, we’ll send a confirmation email to do this. For this reason it’s important that you use an active email address that you have access to. 
• Please note that until the email address has been confirmed you will not be able to upload any content or images to the account.
