Charlee, "Boy Like You" (2010)
Kesha co-wrote this track, which later appeared in 2010 on an album by the Austrian singer Charlee. The lyrics suggest romantic confusion: "Is this all part of your plan? I don't really understand." Though there's nothing uncertain about the pile-driving beat and towers of synthesizers, the song's more hesitant tone may have been the reason it ended up in the hands of another artist — it doesn't align with the freewheeling spirit of Kesha's early hits like "Tik Tok" and "Blah Blah Blah."
