This store is a music collector's treasure trove, with a constantly changing stock refreshed by customers selling and exchanging as well as buying. The main store focuses on rock pop, soul, and dance, both mainstream and obscure, in a variety of formats ranging from vinyl to CD, cassette, and even mini-disk. Don't miss the discounts in the basement and the rarities upstairs. Classical music is at No. 40 and there are branches in Soho and Greenwich.
