Same here. I always get so damn happy when I find a new track that I really like.
I've added a weekly reminder to listen to my Spotify account's Discovery Weekly and Release Radar (based on the people you follow) lists, and I always find new tracks; the Your Daily Mix lists are quite awesome, too, in this regard.
Additionally, I have quite a few Spotify playlists for specific occasions, e.g. gym time; the nice thing about this is that as soon as you start adding tracks to those playlists, you can scroll down and it starts to recommend tracks that you might like based on the ones you just added.
Since I'm quite heavily into Eletronic Music (Deep House, Afro House, etc.), I also use BeatportCharts.com's Advanced Search [0] to find new music that is ranked quite high based on a specific parameter which you can specify, e.g. rank on the charts or number of user likes.
All in all I get so much excitement out of finding new music that it's basically a thing that I do on a daily basis. I'll add Bandcamp to my list of sources for finding new music :)
