Ah, the perfect playlist. In the quest to find a musical oasis where track after track is a pleasant reprieve from the surrounding world, even the best of efforts are often thwarted by limited song selection, an overly complicated user interface, or the lack of insight into upcoming songs. So we’ve scoured the web to find only the best musical offerings and we’ve put together a list of five sites that make playlist building a joy.
You may notice that we’ve left Pandora and Last.fm off our top 5 list. Although we love each site for separate purposes, they both, in their own way, complicate the process of hand selecting and fine tuning playlists that are musical masterpieces. So don’t fret, the 5 sites we’ve include are bound to help you construct your best online mix yet.
