Zune 120 issues...

So I've had a my zune 120 for about 8 months now. After about 2 months, the lock button stopped working, which from what i've read on here, seems to be a pretty common issue. i've tried popping out the switch and re-aligning it, but it just pops back out of alignment after a little while. I'm wondering if anybody has a more permanant solution to this problem.... If I send it in can i be assured that it's not just gonna happen again when i get it back?

Also, lately i've been having another strange issue. A song will end and the track time remaining will show 0.00, but the track time elapsed will keep counting up forever, unless i hit skip. anybody else experienced anything like this?

Not as sure about the lock switch, it just seems to be broken, in which case you'll have to send it out.  You can use your Zune warranty to get it fixed, or have Rapidrepair.com look at the thing

I've never heard of your song time problem before, it seems quite odd.

It might have something to do with the file format of the songs, or maybe some tagging issues

I believe you are experiencing the "infinite time bug" that appeared with 4.0/3.2.  Do a search on it, it has been discussed ad nauseum.  There isn't a fix for it yet, probably will be fixed on next update.
