iPhone Information - Titles

Hello,

If you go on information in the settings app there is a section called titles is there only counting Apple Music? Only downloads?

What I find kind of strange is, I have the completely same library downloaded on my iPad too but it shows about 60 titles more? How can this possibly be?

Is it possible that, cause the device with with more titles is older, removed titled are still downloaded which didn’t download on the newer device?

Thanks
