"But we need the audience to BUY the album" cases?
Can you name some cases in music in which we need the audience to buy the album? I can name a few:
1. Rihanna - ANTI being the future of music with its 2x platinum certification
2. Work From Home and Worth It from 5H being 2 of the 4 most viewed youtube videos on the daily
3. High By The Beach goes Top 10 on Billboard Hot 100 for 1 hour
4. Drake still being #1 on Billboard 200
Considering he debuted with 852,000, spent multiple weeks #1 on sales, and is on track possibly for the top selling album of the year in US the audience has bought the album.
Him spending more weeks at #1 on Billboard 200 even when not #1 on sales is just a bonus.
