in this interconnected ,social media driven, age, it is important that you guard your intellectual property carefully.
In most cases this takes the form of registering publishing rights at minimum via a PRO (SOCAN) and possible registering with any government office of copyright as well
do not under any circumstances register via a non-government entity as in most cases they are simply fronts to scam money from you to do a process (fill in and lodge the forms) that you can easily do for yourself.
paying an attorney to do bulk amounts of registrations is a reasonable thing to do as long as the fees required represent less than the value of your time to do the same task
