There's no set time limit for fair use; it's determined case-by-case by four factors, though general guidelines suggest using small portions (e.g., under 10%) for transformative purposes like criticism or education, while even short clips can be infringement if they take the "heart" of the work. "Magic numbers" like 30 seconds for music are myths, as the amount used (quantity) is less important than how it's used (purpose) and its impact on the original work's market.

Can I use 10 seconds of a copyrighted song?

No, there's no magical "10-second rule" for copyrighted music; using even a short clip can be copyright infringement, as fair use depends on context (commentary, criticism, education) and a judge's decision, not a specific time limit. While shorter clips are less likely to be detected or claimed, they aren't automatically legal, and the copyright holder can still issue takedowns, especially for commercial use where the myth is strongest. 

Can you use a song after 20 years?

Yes, you can use a song after 20 years, but it depends on whether its copyright has expired; most modern songs remain protected for life of the author plus 70 years, but older songs (pre-1978) might be entering the public domain, allowing free use, though you still need a license for specific recordings or new performances. After 20 years, you'll likely still need permission (a license) to use popular songs, but some older, obscure works might become free to use (public domain).

Neither copyright nor trademark is inherently "better"; they protect different things: Copyright guards original creative works (books, music, art) for a long time, while a Trademark protects brand identifiers (names, logos, slogans) used in commerce and lasts indefinitely as long as used and renewed. For businesses, trademarks are often more critical for brand recognition, but many assets (like a logo) benefit from both, with copyright protecting the artistic design and trademark protecting its use in commerce.
