how do I revert back to my current iTunes after re-downloading music from previous purchases under different user name and password
Log out of the account on the device/computer and into the one that you want to use. But redownloading that account's purchases may have tied the device / computer to that account for 90 days, so you may be limited to what you can do on the second account : View and remove your associated devices in iTunes - Apple Support
