I've always liked the idea music-discovery sites and I've found a lot of new favorites while browsing around. My major issue with those sites, however, has always been that they keep interrupting me with new distracting features rather than just letting the music speak for itself. Thesixtyone takes just the right approach to that problem. No unnecessary comments, tags, or album covers, just the music and a nice big backdrop. Enjoy the community of upcoming artists' finest work in the "Hot" playlist or choose one of the mood-specific ones (like mellow, smooth, or trippy) to find just the right track. I wish all music services could pull of a design this clean.
