I wish I could turn to the same genre of music to increase my performance. Like you lyrics are out with exceptions (for some reason I can sort of tune out vocal trance), but some programming I find lend itself well to something like bossa nova, while others I need something highly repetitive like house, and I can't determine ahead of time which will be better. And what really throws me is that usually something like funk will slow me down, but there are times it's the only thing that works. This would all be fine, if I could just roll through the dial, but it takes at least 15 minutes before I know, and it's distracting messing with music until I find something suitable. usually I opt for no music if I'm somewhere quiet, even if there's a good chance music might make me more productive.
