I suppose the drumming tips may not be so relevant here, as JS does most of it for you, but thought I'd mention Pandora Radio.
I've been a member for a while (it's free) and it streams just about anything.
One of my "tests" was to see if The Steve Gibbons Band, The Groundhogs or Atomic Rooster are known, and this site turned them up a treat.
Anyway, they have writing/performing tips at:

Haven't downloaded/heard any yet, but for what it's worth they're free.
I'm registered, don't know if you can access without logging in.
