I tried Genius for the first time on the new iTunes 8 and it worked great. It made me a great playlist that really fit the mood I was in. Music really seems to be evolving in a great direction. Services like Pandora and its musical genome project are cool for finding music similar to what you already enjoy. I found Jonathan Coulton through the service and he was awesome. I find it hard to believe I hadn’t heard of him for so long.
Another service I have been using a lot lately is LastFM. This helped me find some really cool genres of music like Symphonic Power Metal. This tag rocked my world. It is a lot of Finnish and other European bands rocking out with themes about dungeons, fire, demons, and other crazy stuff.
I have never been a huge music buff, but I like that I am able to find a lot of new cool things without having to look like an idiot for not knowing who “Titanomachy” is (I made that up but it would be a kick ass band name).
