Also Checkout a StartUp, Muslate.com, which is based on cloud music and offers unique feature set for all music lovers. I am really impressed with the interface, which is simple but still amazing. Here users can Listen to Popular Music in LISTEN NOW section and can UPLOAD, ORGANIZE their music collection in the cloud absolutely free. Music Sharing is also there on Muslate. I am already in love with this site and i have been using it since past 2 months.
