I've been uploading my Beach Boys related interviews/reviews for years on YT and have never encountered any problems with the music clips I use. Granted, I'm only using the openings and tails of songs because these are edited from radio broadcasts, so we're really only hearing about 5 seconds.

I've had issues with other non-Beach Boys music clips getting tagged for copyright infringement (and some were indeed as little as 5 seconds long). Usually you get a video tagged for "third party content" and all that means is an advertisement will run before your video to generate income for whoever owns the copyright on the song. Whatever software YT uses to identify clips can be quite screwy. I have audio from a 60's movie trailer in a video and YT flagged it as being a song from a 90's band, hence that band now have a little link to buy their music (which isn't in the video at all) underneath my video. I could fight it, I suppose, but it doesn't seem worth the effort.
