bop.fm a unified music streaming platform that simplifies sharing and listening to records from multiple sources online, today introduced a useful “follow” feature for user-created playlists. […] With an ever-growing number of music streaming options on the Web, such as Spotify, YouTube and SoundCloud, sharing your favorite records or newly discovered gems is complicated. If your friends haven’t adopted the same services as you, sending across “share” links is pretty pointless. Bop.fm solves this problem by binding all of these sources into a single portal. – Nick Summers,TheNextWeb
