The Beach Boys' "Smile" was intended to follow 1966's "Pet Sounds." 

Bands occasionally make albums that never see the light of day. Whether due to legal issues or pressure from labels, these records get shelved and go unheard for years or even decades.

But in some instances, this only adds to an album's reputation. LPs like The Beach Boys' "Smile" have gained almost mythical status.

The latest episode of Collector's Crossroads delves into this concept, as some of the greatest "lost" albums of all time can eventually be found. Enjoy a selection of songs from these albums via the playlist below.

Collector's Crossroads airs on CPR's OpenAir Thursdays at 3 p.m., Saturdays at 6 p.m. and Sundays at 4 p.m.
