In music and audio production, Track is used in context as both a noun and a verb.

Noun: A defined audio recording, or MIDI data performance, typically linear in nature, that exists in an organized manner. In other words, the result of recording (or tracking) a vocalist might be called a Vocal Track. Track, as a noun, can exist in several additional forms such as “stereo track,” “MIDI track,” “drum tracks,” and so forth.

Verb: Often used in place of the verb, Record. In other words, to “track a vocalist” infers that you’re going to record a vocalist.
