Okay since update 3.7 to current (3.8 ) the metronome has been broken. (you can't play it, everything else works) It worked in 3.4 on Sansa e200 v1 until the update to 3.8. On the Fuze v2, it has never worked with 3.7 to 3.8. I haven't tested it on anything lower than 3.7 for the Fuze. I haven't tested 3.5 or 3.6 but there is patch for this bug on the Sansa C150. Maybe the patch could be applied to the Fuze and e200 in the next release.
