“Guardians of the Galaxy” continues to do well not only at the box office but in record stores.

The soundtrack to the Marvel blockbuster, which features mostly '70s and '80s tunes,  is spending its second week at number one on the Billboard Album chart, selling 93,000 more copies.

Interestingly, thanks to “Guardians” and “Frozen” soundtracks have spent 15 weeks on top of the Album chart, which is close to half of the year.

Coming in at number two for a second week is the Now 51 compilation, followed by “Frozen,” which saw a 53 percent increase in sales.  All three top albums feature various artists, the first time that’s happened since  April, 2009 (“Now 49” and soundtracks to “Hannah Montana: The Movie” and “Twilight”).

Elsewhere on the chart,  The Gaslight Anthem’s latest  “Get Hurt” marks this week’s highest new entry at four, followed by 19-year-old YouTube star Troyve Sivan’s EP “TRXYE” at five.
