As the others have stated, we all grieve in different ways. You may find that after a while (or even a short period of time) that you may suddenly feel a wave of grief. This would be perfectly normal. I remember when my Granddad died I couldn't cry at his funeral, but later on I felt really sad and (sometimes) angry. The important thing to do is to talk about it with your family. It will be like a weight off your chest. This will allow them to understand your grief, and so if you feel angry and lash out then they will understand why.
Sometimes it's good to channel your feelings, but try not to become self-absorbed. It can lead to all sorts of trouble; depression for one. The same for music. Listening to music can feel good, but certain never take lyrics in songs seriously. A good example is Eminem. He's an excellent lyricist, but a lot of what he says isn't true, or doesn't reflect his true feelings.
I hope this helps
