I hear this often and have asked it ask too many times to count. Over the last few years I have found some resources that have been very useful to me. Most notably is the CoreWorship.com site. As long as it is available it is worth checking out. It costs about $30 a month (less if you pay upfront) and offers part tracks,lead sheets, chord charts, and loops (my personal favorte). There is another club that is similar and it is Mark Condon's music club.
