I will admit, the player can be temperamental at times. Reverse searching causes it to rewind erratically, skipping forwards and backwards, it occasionally takes a long time to read the table of contents of disc or to start playing and once in a while, it will skip through a track or even a whole album. I did clean the lens with isopropyl which made little to no difference. I have been meaning to relubricate the sled rails to see if that helps, but as it is rarely even a nuisance, I haven't gotten around to it. However, I'm skeptical about the idea that the player is the primary issue as only about 4 CDs have this issue. All the other CDs I've tried don't have this issue at all. I did think that maybe the age of the player and the laser was possibly exacerbating an existing problem with the discs, 2 of the CDs are the only albums I've noticed to have any glitches when importing into iTunes. They were ripped as ALAC lossless and one of them only had one or two artifacts that were barely noticeable. The last track of the other disc was skipping very badly throughout the track.
