Thanks All for replying. At least I know it is not just my unit acting quirky.
I found out since posting this that the love button does work as usual on some stations, stations that I do not listen to

. BUT... I also found out that on the station that I have had my S50 locked to for the last 3 or 4 years works on only some songs! Unfortunately it seems like it works on only 1 out of 25 songs.

So I guess it is song specific now. The station I listen to is one of the stations that combined similiar Sirius and XM stations into one common station. But I don't think it comes down to the old sirius songs working and the XM don't. You see... both stations, even though they play the same genre of music, were pretty good about not playing the songs the other was playing. So now there are more songs to listen to. But as I said, the love button does not seem to take this into account.
If this is something new with the merger I would think that Sirius would have to make some sort of statement, at least for those that might buy the Stiletto in the future. It does not work as advertised anymore!
Chombi, I cannot record anything at all when it asks to press to start and stop recording. If you can at least I'd be slightly happy.
