node-taglib-sharp / Exports / Mpeg4AppleTag
Abstract class that provides generic access to standard tag features. All tag types will extend this class. Because not every tag type supports the same features, it may be useful to check that the value is stored by re-reading the property after it is set.

• get album(): string
Gets the album of the media represented by the current instance. For video media, this represents the collection the video belongs to.
This field represents the name of the album the media belongs to. In the case of a boxed set, it should be the name of the entire set rather than the individual disc. In the case of a series, this should be the name of the series, rather than the season of a series.
For example, "Kintsugi" (an album by Death Cab for Cutie), "The Complete Red Green Show" (a boxed set of TV episodes), or "Shark Tank" (a series with several seasons).

• get albumArtists(): string[]
Gets the band or artist who is credited in the creation of the entire album or collection containing the media described by the current instance.
This field is typically optional but aids in the sorting of compilations or albums with multiple artist. For example, if an album has several artists, sorting by artist will split up albums by the same artist. Having a single album artist for an entire album solves this problem. As this value is to be used as a sorting key, it should be used with less variation than performers. Where performers can be broken into multiple artists, it is best to stick to a single name. Eg, "Super8 & Tab"
