musical work/composition
constraint clarification
"musical work" and "musical composition" mean the same thing so we just use "musical work/composition". The reason they are still separate items is because we can't merge them due to some Wikipedias still having articles for each. (English)
"יצירה מוזיקלית" ו"חיבור מוזיקלי" אומרות אותו דבר אז אנחנו פשוט משתמשים ב"יצירה/לחן מוזיקלי". הסיבה שהם עדיין פריטים נפרדים היא בגלל שאנחנו לא יכולים למזג אותם בגלל שחלק מהוויקיפדים עדיין מכילים מאמרים לכל אחד מהם (Hebrew)
