You could tell how good the album was by where they placed the banger. If it was the last song on Side A, then you knew the album was going to be solid. If they put the hit song on A1, that meant it was probably going to be trash because they don't trust you to make it through 3-4 more songs before getting to the one you bought the album for. There are always notable exceptions -- they put the hit song on the end of Record 2 side B and then it wasn't even credited on the album (Train in Vain). But that album is 2 records of excellent songs with the possible exception of Jimmy Jazz.
