All downloads from the store are tied to the account that downloaded them, so if those songs were bought by that old account then only that old account will be able to authorise them. If you can't remember the password but you know it's security info then you could try getting the password reset via this page : http://iforgot.apple.com - if you can then you can change the primary email address on it by logging into the account : http://appleid.apple.com
If you can't get the password reset that way then you could try contacting iTunes Support : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page
Or maybe Apple : http://support.apple.com/kb/HT5699
