Is music from the 60s and 70s still copyrighted?
The answer depends on whether you mean sheet music or recorded music; they each have their own copyright and expiration. One may expire without affecting the other.
More than likely, yes. In general a US copyright is valid for the life of the holder plus 70 years, or 95 years from publication, if done as a work for hire.
However, the duration of a particular copyright can get complicated in the area of "music" and "sound recordings" of music that happened to occur in the 1960s and 1970s.
First, consider that federal copyright does not include any sound recordings made prior to 1972. State laws, however, cover sound recordings and those laws do not have any expiration (unlike federal copyright), at least not until pre-empted by federal copyright law in 2067. Thus, you must consider ALL pre-1972 sound recordings to be copyrighted until then.
On the other hand, the underlying "music", as a composition of notes (and maybe lyrics), may or may not be protected, depending upon when it was created or published, and if a renewal was filed. A related answer addresses the question of copyright duration in more detail.

There was a movie that was made you believe n the 60s or early 70s where money was hidden in a dall what movie was it?
Unfortunately, I doubt that any country today has a population that favors metal music over any other. The 2000s (and now 2010s) are the age of Pop and are now reviving forms of electronic, rap, and dance music. Metal music was most popular in the 60s-70s in the US and UK. Today, metal music has transformed and infuses different styles of music into it, such as hip-hop. It still remains somewhat popular in the US…
AM radio is now dedicated mostly to news/talk formats but not FM, which still carries musical content for the most part. FM has a larger bandwidth than AM, so FM offers much better sound quality, which is well suited to music. Talk radio doesn't require the fidelity that music radio does. The switch-over started in the late '60s and and '70s.
