Really sorry for your loss. If s so sad. We have a kitty who’s getting up there in years. We had to put down her bestie earlier in the year (check my post history), and she’s the next oldest. We’ve been mentally preparing ourselves ever since to say goodbye to our awesome oldest cat. Again, sorry for your loss.
There were a handful of them. Two I remember are allofmp3 and something like mp3eagle. One of those introduced me to Muse around the time Black holes and Revelations came out.
