The LHCb experiment is a forward arm spectrometer designed to make high precision measurements of b hadron decays at the LHC. During 2011 a total luminosity of 1.0 fb-1 of data was collected at sqrt(s)=7 TeV. LHCb's efficient dimuon trigger allows to perform studies of B mesons decaying to charmonia with high precision. We will present new measurements of the relative branching ratios of exclusive b decays to final states involving J/psi and psi(2S) mesons, together with other studies of B-decays into J/psi and light hadrons. In addition, we will discuss results for exotic states such as the X(3872) and X(4140) .
