I think the pitfall is that they take too long to release a second album; they need to ride that wave of the first album and quickly send out a second album of decent quality; key example being Lady GaGa. Had she not done that, I think she'd have fallen into that category of having a difficult second album, but because she quickly released more material, it's cemented her position and she can take a break now. Most artists make the mistake of taking a break between their first and second album, which in my opinion is where they fall flat on their faces. Paolo Nutini, The Kooks, The Fratellis... the list is endless.
