Hello there, maybe this is a stupid question, but I wanted to know, if you overplay a CD, will the sound quality be affected? Here's what my CD sounds like: On the first track of the disc the sound on the left speaker sounds a little muffled, like the treble has been decreased. But the sound on the right speaker sounds just fine. All the other tracks on the CD sound perfect on both the speakers, so I know my stereo is not the problem (all the other discs I play sound fine). I bought this CD used. If the previous owner of the CD overplayed the first track on the CD, could they have affected the sound quality that way? Would it make sense that only one speaker of sound is affected? Sorry if this seems stupid. Thanks!
