Pitch masses are fairly common on this type of tree.  My first inclination is that it is caused by an insect known as pitch mass borer, however, without a close up photo and probing with a knife, you cannot accurately determine that.  Norway spruce are also known to exude copious amounts of pitch from pruning cuts where the limbs have been removed.  This is not an issue  but if you start to see decline in the canopy (yes- I think I see some of that) you may want to procure the services of a certified arborist to come check it out.  This link will allow you to search for an arborist by zip code.  https://www.treesaregood.org/
