What early Pre-Rumours era songs do you consider to be "hits"?

[MacShadowsBall]

So on the Rumours forum I'm running a contest to find out the favorite non-hit Fleetwood Mac. Ledgies over there have varying opinion of what can be defined as a "hit". Do you go by the songs that were released as singles and charted well, how well and which charts, what if the song is recently discovered and now is well-liked?

So post the songs you feel shouldn't be eligible in the favorite non-hit song contest.

Thanks!
