Currently, artists just release singles with 1 track - the song.
For example, Ariana Grande's single "Focus" has 1 track:
But wouldn't it be better to release additional tracks as well, like the backing track, instrumental, and acapella:
backing track: no lead vocals, but includes the backing vocals
instrumental: no vocals at all
acapella: only vocals
I think there is market demand for such additional tracks. People want backing tracks and instrumentals for karaoke; aspiring singers want backing tracks and instrumentals for covers and singing competitions; comedians want backing tracks and instrumentals for spoofs; DJs and producers want acapellas for remixes.
So, following that idea, a single like Ariana Grande's "Focus" would have 4 tracks:
Focus Focus (Backing Track) Focus (Instrumental) Focus (Acapella)
Here's another idea: Selling the producer's project files. Aspiring producers could study them; DJs could use them to create remixes.
No? Am I missing something?
