CSPC: Grease Popularity Analysis

Missing piece of the puzzle

Full Length related records Sales

You may wonder why this section exists as you can hardly release greatest hits or DVDs out of a soundtrack. If John Travolta never had proper compilation albums either, both Frankie Valli – along with his past band The Four Seasons – and Olivia Newton-John had various compilations in post-1978 that included their respective Grease singles. Let study how much those songs contributed into their hits albums.


How to understand this table? If you check for example The Four Seasons compilations album line, those figures mean they sold a combined 3,000,000 units worldwide. The second statistics column means all versions of all songs included on this package add for just over 104 million streaming plays on Spotify as of August 24 2016.

The second part at the right of the table shows how many streams are coming from Grease album plus the share it represents on the overall package streams. Thus, streaming figures tell us Grease songs is responsible for 13% of the all Four Seasons compilations track list attractiveness, which means it generated 400,000 of its 3,000,000 album sales and so on for the other records. As a notice, I usually perform those statistics on specific albums. In the case of both Four Seasons and Olivia Newton-John, they released a large number of career spanning compilations with roughly the same 20-hits tracklist. I used the share of their respective Grease hits among their respective Top 20 hits.

As you can see, I also noted N/A for streaming details of Olivia Newton-John. Indeed, while Grease songs represent 79% of Greatest Hits II attractiveness and 67% of the latter, more comprehensive compilations like The Essential, I voluntarily downgraded their share. Why so? Quite simply because her solo hits like Xanadu, Physical or Magic are now deleted from Spotify, which artificially inflated the share of the likes Summer Nights and You’re The One That I Want among her results.

I always tried to avoid approximations as much as possible. In this case the impact is still fairly limited as sales-wise all those albums except 1982 Greatest Hits II managed low sales.
