Is there an easy way to check for new episodes, albums, etc.?

I watch a lot of shows and listen to a LOT of music. In the process of googling all of those things a million times to check for new releases I started longing for a program that allows me to put all these things in a list and then to quickly check for official releases using a reliable database.

So my question is if anyone knows of such a program. Thank you for reading.
