I loo-ve the word groovy, do you?   Best part about it is that it originated from the jazz music culture, as far back as the 1920s, far pre-dating its' every day use as slang, ca. the 1970s.  

Celebrate groovy.   Song titles, song lines -- any music you can think of that has groovy, the groove, groovin, anything at all.  I want to hear it. 

ETA: Personal remembrances of groovy, baby, are welcome.  What ever makes you happy.   

BRING GROOVY BACK.  :)
