Narrative:

The captain and I had loaded and briefed the arrival and approach with the expectation of receiving the visual backed up by the ILS to runway 2R bna. When we checked on with approach the assigned us 2L. We were confused but complied. Reloaded the FMS; re briefed the new runway and ran the runway change items. We were given a descent to 2600 then a right base turn. And when runway 2R was abeam our right wing tip approach told us we were cleared for the visual 2R. The captain read it back. Neither one of us realized the approach controller had said 2R instead of 2L. Nor had we realized the captain read back 2R and didn't double check that they in fact meant 2R and not 2L. While manually turning in to intercept the localizer for 2L we both heard the controller then tell ('air carrier X' similar sounding callsign to 'air carrier Y') they were cleared for the visual 2L and not to worry about the [other traffic] that they were going to the right side. We both quickly realized what was going on. The captain keyed the mike and confirmed 2R we made a right turn to heading 050 intercepted the final for 2R. We agreed that because we had briefed 2R initially and had landing numbers for 2R we were both comfortable with continuing to a full stop landing on 2R and we would figure out what had happened on the ground. If you had asked me in flight what the controller said I would bet my life that we were cleared for the visual 2L... But after reviewing the tapes it was very clear we had made the mistake. Expectation bias I guess... Late last minute change by approach with no heads up... Multiple factors played a key role in this incident.
