Thank you all for the great suggestions on using the features of BB/RB and the links - I hadn't thought of using those features of the program to explore harmonies, and the links are exactly pertinent also.

Stylewise - I'm 'locked' into the songs I group up with - I love multipart harmonies and the arrangements from the old groups such as the Eagles, Beach Boys, Abba, Chicago, Fleetwood mac. I would love some suggestions on some newer music to listen to that is a little more 'modern' (e.g. not decades old !!!) and has songwriting just as solid as these old megagroups.
