That One Song tells you what a band sounds like

Heard of a band but don't know what they sound like? Sure you could Google it (like a normal person) but you're more likely to turn up the band's most popular, and not necessarily most representative. song.

That One Song, by the makers of social music website This Is My Jam , aims to change that. The app aggregates the listening habits of Jam listeners and finds the "best" or most shared song from each group and provides results in the form of Spotify and/or YouTube links. You don't need to be a This Is My Jam subscriber to use it, either.

The interface is simple -- just a search bar -- and the catalogue is seemingly extensive with searches on both obscure '90s antipodean acts (Sandpit/Loves Ugly Children) and Icelandic medieval groups (Voces Thules) failing to flummox it.

But while most results were "deeper cuts" rather than obvious singles -- it chose Pearl Jam's "Black" instead of "Alive", for example -- it sometimes chose songs which weren't representative, such as hair-metal band Extreme's popular "More Than Words."
