While The Four Seasons movie "Jersey Boys" might be off to a slow start, interest in the band's music appears to be heating up. 

The 2003 compilation "The Very Best of Frankie Valli & The Four Seasons" held the top spot on the Amazon bestsellers list Monday.

The 20-track set features such classics as "Sherry," "Big Girls Don't Cry," and "Walk Like A Man" along with Valli solo hits including "My Eyes Adored You" and "Grease." 

Meanwhile, the "Jersey Boys" movie soundtrack, which arrives in stores today, was at No. 4.

"Jersey Boys," which hit theaters last Friday, earned just $13.3 million in its opening weekend. 

However, BoxOfficeMojo.com reports the film is attracting an older audience, so it could see steady ticket sales for several weeks instead of opening big then dropping off significantly. Adults older than 50 years old accounted for nearly three-quarters of "Jersey Boys'" opening weekend ticket sales.
