I just bought a sansa clip+ and have found (after a lot of trial and error!) that tracks which contain album artwork in the tags are a lot slower to skip to (1.5-2 seconds) than those without (almost instant) - i found this quite irritating when trying to skip through multiple tracks…
Personally i don’t use the album art feature on my PC so i stripped them from all my mp3s using mp3tag - this has solved the problem, but obviously adds an extra step i’d rather avoid if possible.
Is this issue known? is there a solution? could a solution be featured in any future firmware update? (currently running latest v01.02.09)
