I'm hearing things

I wonder if anyone can explain why this happens. Between tracks I sometimes hear the start of the next track before it happens! I hear a very faint rendition of the first bar before the music-proper comes in. It's kind of ghistly and rather disconcerting! This is only discernable when I listen to a record with the volume quite high and I don't think it's with every record I own.

What causes this? Is this a fault or feature with the record pressing itself or due to some incorrent alignment/setup?

Any help, very much appreciated. Thanks.
