Is my favorite song a classic?

If a song is 0 - 10 years old, it is considered new.

If a song is 10 - 20 years old, it is considered a classic.

If a song is 20 - 30 years old, it is considered an oldies.

If a song is 30 - 40 years old, it is considered a golden oldies.

If a song is 40 + years old and still getting air play, it is a platinum oldies. (my own classification)
