Running an automatic Twitter campaign is also fairly simple with WP Content Pilot. You will need a SoundCloud client ID to proceed with the campaign.
In order to get your client ID first, you have to sign in to your SoundCloud account. Sign up here if you do not already have an account.
You have to access the Developers from the drop down to create your first app. It is unfortunate that due to a higher number of app requests SoundCloud has suspended the creation of new apps.
SoundCloud has promised to review this and allow us to create apps that are more efficient.
In the meantime, you can grab a client id from your friend or family.
