So on the flats or downhills, the music is a pleasant accompaniment. My main criterion to put a tune on my playlist is "Do I want to hear this while struggling up a hill (and do I want to hear it more than once, since it is on my playlist)?".

BTW, don't knock Lawrence Welk; he had good musicianship. If you object to his tunes, IMO, Big Band standards (and Classic Rock) are great for cycling.
