Should I have a separate blog for a band page?

I love blogging. Should I just continue blogging my whole life on one blog, or have it separate. Some things I’m considering to separate. 1. A separate art blog full of my art works. (should I separate my photo blog from my paints and drawings?!) 2. A separate band blog where I post only music related things. 3. And have a separate blog where I post about my troubles and thoughts of normal life, and post family things and such.

Help! Major internet schizophrenia!
