- Themes. Each round, or some rounds, could center on one theme, which could be music from an era, say the 70's, from the soundtrack of one specific movie, or bands - presumably well-known - which are linked through one band member. Etc. The basic idea here is that you need to get the majority of the songs right in order to get the bonus points, or it's welcome to Guessville, population You. In other words, for each round, to whom doth possess much, more shall be given.
....comments or suggestions for more ways to introduce bonus points? Especially if each installment is limited to 50 songs or less, there is a need to separate the field more than what's been the case up until now. However, a bonus question like "who was the bass player on the original recording of this song" is quite, quite useless when everyone and their mother can look it up on the interweb provided the song has been found. Unless that's ok by y'all - the possibility of bonus points based on recognizing specific songs and using Google-Fu for the additional info needed.
Let's hear it.
EDIT: Of course the idea with the themes would be that you get bonus points by figuring out what the theme is. I guess that wasn't very clear from the text.
