CD player making strange noises

When I turned my stereo on today and put a disc into my cd player, I could hear the disc spin through my speakers. Then when I hit play, I kept hearing small pops and cracks come through my speakers. Any thoughts on what's going on? Everything else in my system works fine.

Any help would be appreciated.
One of my friend CD player did the same thing and then the power transformer was gone .
The motor noise thru the speakers is probably a defective or loose noise filter (capacitor) across the motor terminals. The pops and crackles are probably dirty/oxidized/loose connections here, there or everywhere. I also agree with Edle - the power supply may ready to quit.
