Well if you have a very good Albanian accent, then r is not rolled because in Albanian we have 2 r's in the alphabet 1 that's just R and RR which is rolled.
do te shkojne = jan tuj shku
and q is not like a vert soft t, its like a Ch sound like i said, except it is pronounced a bit differently, and GJ is like the j in jogging, because albanian G is like the g in games and albanian J is like the y in yes
and some singers have better accents than others, sometimes, singers from south have very 'balkan' sounding accents, but if u heard for example albanian television hosts from albania speak on television they usually have very good accents
*btw my gheg is not very good because i am a tosk speaker, i am just trying to use examples i understand to help you understand the differences, in most cases this is why i do not translate songs in gheg because i do not want to mislead anyone if this is the dialect they are learning in
