In lui of a playlist I created, check out Songza. This is a my new favorite website (and smartphone app!) for streaming music. The site is full of ready made playlists by DJs. Although it may seem like all the other streaming sites, Songza differentiates itself by being free and without commercials. It also allows you to filter by mood, genre, decade and activity. One downside is you cannot request a song or artist that you like, however, the descriptions of the playlists are spot on and you get what they say you get. There are mixes for working, sleeping, partying, even yoga.
Some of my favorite playlists are:
Yoga: Elevation of Spirit (found under Activities>Yoga)
At a 90s School Dance
The Golden Age of Boy Bands
Feelin’ Good in the 90s
