I created a new kind of exercise, with dropdown suggested answers, so you don't need to write while listening to the song, but simply click on the option you hear. You can also try to do the exercise before listening to the song, in order to guess what's missing.
I guess it is just the perfect time to learn a bunch of commonly used phrases and collocations in Serbian with a newly released song "Sistem te laže" by Beogradski sindikat.
Make sure you listen to the song once again, following the same lyrics in the Cyrillic script!
