SDM - Dobra wiadomość
SDM has been categorized as "student music" because its lyrics focused largely on love, adventure, and hiking in the Polish mountains.  But in
time they developed their own style for which they became famous. Their musical style evolved into what can be described as acoustic blues.  
Many of their compositions were based on interpretations of poems written by the well known Polish poets such as Edward Stachura, Adam
Ziemianin, and Jan Rybowicz (whose work focused on aspects of human existence).

Some of their songs are Zabieszczaduj, Tymbark, Wiersz o płaczu (Poem about crying), and Najważniejsze jest (the bottom line is) among others.
