With six shops over Barcelona, Castelló pretty much has the CD market sewn up. Half of them are located in the Calle Tallers, a street of door-to-door music and vinyl shops. Opened in 1934, their flagship store at no. 7 is mainly pop rock. Next door, "Overstocks" has more of the same plus sections on jazz, world, Spanish, and country music. Classical music is sold at no. 3.
