Using music multiple times in a podcast series

Hello,

I bought a few music themes and used them in my podcast. If I am running a series (up to 52 episodes within a year) I understand I can use such music in all apisodes and multiple times within each episode? Like a background music, 3-4 times in each of 52 episodes? Even if there is a different voice over them? As long as it’s a one series it is ok?

Thanks
