Tuneglue-audiomap will recommend users to particular artists based on their listening preferences and by matching them to the choices made by other music fans.
EMI said its artist directory was not limited to EMI artists, such as Robbie Williams, Hot Chip, Sigur Ros and The Magic Numbers. The service would also provide website links, artist biographies, competitions and sign-ups for the label's bands.
Eric Winbolt, digital media manager at EMI Records, said: "Tuneglue-audiomap is tapping into the power of Last.fm's music recommendation engine and is connecting bands and artists based on what the Last.fm users have chosen to listen to.
Martin Stiksel, chief communications officer at Last.fm, added: "Last.fm's mission is to connect people with the right music and tuneglue-audiomap is helping people do just that in a very intuitive, visually interesting way.
"You can pick any band as a starting point and before you know it you are discovering artists you have never heard of before."
