Throwback Thursday - 45's with stacker

Do you remember 45 RPM records?  And '45 stackers, like the one pictured here?  We used these on my little record player as we roller skated in the basement.  I remember the sound of the record dropping, the record player arm moving.  I haven't played vinyl in years (alas, I know - my loss!), but this sound was such a part of my childhood.  

Did you grow up with 45's?  I'd love to hear your memories in the comments, below.
