I use all songs available on Spotify by In Flames. It's mostly melodic and rhythmic, usually upbeat, and the vocals and the higher spectrum percussion drown out ambient discussions without being very thought-provoking in themselves.
Hello there metal fans, I enjoy tuning in people's MDM broadcasts on Grooveshark. With suggestions its a nice mix of background music you don't have to manage and occasional song that you would like to hear.
Yes yes! I'm a fan of Metallica but I can only listen Kill'em'All while programming. Either that or repetitive ambient/instrumental/chill-out without vocals.
