Locked Apple account for specific songs on iTunes

Cleaning my music db, I encountered one, then a second songs I purchased on Apple iTunes store that asked my password to allow me to play them. After inputting my password that worked to log into iTunes, I get the error message "This Apple account has been locked for security reasons. Visit iForgot to reset your account."

After resetting password twice, I still am locked out of these songs. What am I supposed to do? Other songs purchased with the same account are working fine.

thanks for your help!
