I have several playlists on Spotify:
'Move that body' -with my favorite dance music. I guarantee you I just can't sit still when I put that on.
'Happy Happy' -songs that make me happy and singing
'Memory Lane' -my all time favorites that reminds me of good times in my life
'S' -songs that remind me of 'S'
'Something that turns you on..' -don't think I need to comment further ;)
