Мій приятель не слухав музику в віаторок.
There doesn't need to be an article before 'music'. (Scowl)
This should just read "My friend did not listen to music on Tuesday". No need for THE. Also, what is happening with Вівторок? Do we need not add an а or anything to words ending with к in ukrainian?
Not in the accusative case. It matches the nominative case for masculine inanimate nouns.
Okay, thank you :)
