The power of a classic: despite being 42 years old this year, Pink Floyd's The Dark Side of the Moon shows no sign of waning or losing popularity. The album, according to the US information and sales tracking company Nielsen Music, is one of the 10 best-selling vinyl album for the first half of 2015. The album is at the number seven spot of the 2015 Nielsen Music US Mid-Year Report's Top LP Vinyl Albums list, selling 22,600 copies this year so far.

Their report notes that vinyl record sales have increased by 38% from last year, and comprise around 9% of all physical album sales. The Dark Side of the Moon, being a sonic feast, needs to be heard on a decent quality slab of vinyl, so repeat purchases, replacing scratched and crackly copies, have aided sales - although the band are continuing to pick up new fans, and TDSOTM is a great, and commonly selected, starting point for those wishing to explore their catalogue.

To date, the album is believed to have sold in excess of 45 million copies, and is one of the biggest selling albums of all time, along with albums such as Michael Jackson's Thriller, AC/DC's Back in Black, and Meatloaf's Bat Out of Hell.
