I don't know man. My mum says all Mark's songs sounds the same, I guess it just your prefrence.
This is in my opinion (and absolutely no offense to your mum, Pavel) something someone with little knowledge of the artist would say.
I don't know your mum's musical knowledge of MK, ofcourse. So please correct me if i'm wrong.
But take my 2 nephews for instance,
One listens to The Beatles and The Traveling Wilburys
And the other one listens, almost exclusively, to Jerry Lee Lewis and Fats Dominos etc.
When asked about their opinion on MK and DS they say: It sounds all the same, it's too slow and long and therefore it's boring to me
I bet you if i asked them they could barely name me 5 DS songs and maybe 1 MK solo song.
The songs they know are TR, SOS, WOF, MFN. The "mega" hits.
Yes, Telegraph Road is over 14 minutes with 3 guitar solo's. Yes, Brothers In Arms is a slow song. But these are some of the best songs ever written. And then to say the music is all the same and boring? Of course people have a difference in music taste but that, for me atleast, indicates a person with little knowledge of the artist.
Take Mark's "Golden Heart" album. Compare the title track GH and a song like "Darling Pretty". They're on the same album but the songs are so different
Take "Vic And Ray" and "Imelda". Again, same album and completely different songs.
