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, comics and books on nearby Pembridge Road, and there are branches in Soho and Greenwich.
