I'm still excited, although sometimes I work hard to mix it up, change genres, etc. so that I don't start to feel fatigue.
There are certain artists, however, who used to excite me, but for whom I now have a difficult time getting excited. I find that very frustrating. For example, there was a time when Stan Getz really excited me. I bought almost all of his records. Now I still enjoy listening to Getz, but I can't get back the real excitement that I used to feel. I listen and think that I should be enjoying this more than I really am.
