That's a common saying, and it holds some truth to it. Music can certainly transcend linguistic and cultural boundaries in many ways:

1. Emotional communication: Music can convey emotions that are universally understood, even without words.

2. Rhythmic patterns: Beats and rhythms are often consistent across cultures.

3. Universal themes: Love, joy, sadness, and other core human experiences are frequent musical subjects.

4. Shared experiences: Concerts and festivals create communal experiences worldwide.

5. Cross-cultural collaboration: Musicians from different backgrounds regularly blend styles.

6. Instrument recognition: Many instruments have global equivalents or analogues.

7. Dance: Musical elements often inspire universal physical responses.

However, it's important to note that:

- Different cultures have distinct musical traditions and preferences.
- Lyrics are often culturally specific and not universally understood.
- Some musical concepts don't translate easily between cultures.
- Personal taste in music varies widely between individuals and societies.

So while music has the power to connect people across borders, it's not a perfect universal language like mathematics or certain forms of logic. It still carries cultural baggage and personal associations that can vary significantly.
