Sev has musical tastes as eclectic as her background. Trained in classical flute and jazz/blues piano, she also has a deeply abiding (and rather dominant) love for techno, dance/club music, and either fantastically good or severely awful songwriting.
She also has musical ADD, which would explain why her stations are so varied and why she is constantly thumbs-upping or thumbs-downing things based on her mood or blood sugar.
She's currently addicted to the Blackberry Pandora App, which explains why her stations are all so new; she deleted old ones to remake new better ones. Also, she uses Pandora mostly at the gym or while driving, which explains the prevalence of embarrassing/awful/ridiculous techno, club, and dance music in her stations. She'd like to think that someday she'll develop an awesome jazz channel but as she hasn't found jazz to be quite as motivating during a 5K run as a good bumping techno bassline, that day has not yet happened and is probably pretty far off in the future.
