Alternative dance (known primarily as indie dance in the United Kingdom) is a term used for the genre of music combining elements of dance-pop (or other forms of electronic dance music such as house or techno) and alternative rock genres such as indie pop. Alternative dance music is typically predominantly electronic, with programmed beats from drum machines or sampled drum loops and sequenced synthesizer melodies, and thus musically very similar to commercial dance-pop. The indie element is most prevalent in the songwriting; unlike much dance music, alternative dance typically contains lyrics, and, as in indie pop or indie rock, these are often more thematically complex and/or less polished than those of commercial pop.
