"No song" when music is on external SDHC card

Is this new player actually “new” or did you buy it as a re-furb? The Clip+ has been discontinued for somoe time now, and availability is scarce (and expensive). Re-furbished players (actually all electronics) are risky as they have been previously returned, ususally for some problem or defect and then sold off in bulk to refurbishing companies. Many times the original defect or issue is never resolved.

Either way, sounds like the card reader in the player is wonky. If you have any warranty or exchange options with whomever you bought it from, I would take advantage of those.
