CD glitches

[Yachtingtype]

Hello,

I hope this is the correct place to post such a topic...

For the last few days I have been uploading my entire CD collection on to my MAC and have came across a few glitches in select songs, can anyone else here confirm the glitches appear on your disc as well? Here is what I found so far,

LENE LOVICH - BE STIFF (about 16 seconds into the song)
THE BEST OF THE STIFF YEARS VOLUME 1

RUPERT HINE - INNOCENCE IN DANGER (not even a second into the song)
WAVING NOT DROWNING

HOLLY & THE ITALIANS - MILES AWAY (does anyone else hear that glitch when the song first starts? My vinyl copy certainly doesn't have that sound)
THE RIGHT TO BE ITALIAN

HOLLY & THE ITALIANS - DO YOU SAY LOVE (again, as soon as the song starts there is that small glitch)
THE RIGHT TO BE ITALIAN

I just want to make sure these are not just my CD copies

Thank you
