I rediscovered music about 5 years ago when my life hit a low. It consoled me. It spoke to me. It calmed me and it inspired me. Somehow music must be part of the fabric of the universe which we are part of. It is literally food for the soul.
I like Celtic music because it is so soulful (Loreena Mckennitt, Qntal). I love great female vocalist whether it's pop or Middle Eastern or blended styles (Dido, Azam Ali).
But, I love electronic most. I got started by wanting to learn who did the opening sound track score to Chow Yun Fat's Replacement Killers. The track was Keep Hope Alive by the Crystal Method (still an all-time favorite of mine). The matrix sound track led me to Juno Reactor (Mona Lisa Overdrive). As I found more music I became inspired to find more and more...
There is so much great stuff out there. I mean, I feel like a lot of people out there think music ended after Mick Jagger. My God: it's changed and it's going to keep changing and I hope I never stop exploring. There's a wonderful world of music out there!
I use Itunes and 90% of my 10 gigs are electronic. I like particular artists in synthpop, EBM and some harsh Industrial. It's funny; I thought that just because I liked Electronic music everyone else who liked electronic music would like what I like. But instead I learned that musical tastes are as varied as tastes in finding a mate.
Here are some of my favorites beyond the more commercial (ala the Crystal Method, Chemical Brothers) that people should absolutely try: Mind.in.a.box, Neuroticfish, VNV Nation, Assemblage 23, Covenant, In Strict Confidence, Seabound, and Frozen Plazma.
My latest great find is Pandora. I was going around in circles with Amazon's and Itunes recommendations. I wasn't finding anything new. Then I started listening to Pandora and it has reinvigorated my searching.
Have fun and keep listening. It's good for the soul.
