shining bright wrote:One thing I don't understand: is it so hard for the two of them to work together on songs instead of having 7 songs by Mart and 3 by Dave ( or 6 and 4, 5 and 5...)?
Or would this mean that none of them would be able to express themselves fully?

i'm not a musician but following some logic, i assume they just don't click when it comes to composing, Martin is probably used to working alone, and can't mix his inspiration with someone else's...
i imagine him having a train of thoughts and ideas and then comes dave with a different perspective while martin knows exactly what he wanted to do.
i dunno. just guessing here
i always thought that dm simply could not exist without martin OR dave, cause martin isn't the showman and master on stage as dave is (and although i adore mart's voice, and i really can't say who's a better singer cause they're both incredible; dave's is probably more ''right'' for the band) and dave is not such a genius composer as martin is.
