I have a love affair with electric guitar. The number of different sounds and styles an electric guitar can produce is amazing to me. I love music that features a skilled guitar player as the lead. Therefore, I love the work of Steve Vai, Joe Satriani, Joe Stump, and Gary Hoey.
I also have a love affair with the piano. I took piano lessons for a year but gave up cause the teacher was old and taught me as she would teach a 4th grader. Anyway, I love skilled modern piano musicians, the likes of Ben Folds, Elton John, and The Decemberists.
I also have a love affair with nerdy things, like video games and movies. Music that establishes a mood and is not dependent on lyrics for meaning is awesome. I love the soundtracks of RPGs and AAA movies. This has spilled into a love of electronic music, such as Ulrich Schnauss and Daft Punk, and chip-tunes, such as Anamanaguchi.
