Last.fm client constantly scans Wi-Fi networks

[mrvacbob]

Running the Last.fm app 2.1.36 on OS X, with "fingerprint my tracks" unchecked, I see it asking for the current wifi network every minute.

4/15/14 7:39:50.000 PM kernel[0]: IO80211ScanManager::getScanResult: All scan results returned for 'Last.fm Scrobble' (pid 1679).
4/15/14 7:40:00.000 PM kernel[0]: IO80211ScanManager::startScan: Broadcast scan request received from 'Last.fm Scrobble' (pid 1679) ().

4/15/14 7:40:10.000 PM kernel[0]: IO80211ScanManager::startScan: Broadcast scan request received from 'Last.fm Scrobble' (pid 1679) ().

This could be a serious battery drain issue - "sudo systemstats -J today" for me shows Last.fm causing the most CPU wakeups behind only kernel processes.

OS X's battery menu list of power draining apps only shows apps with dock icons, so I wouldn't see this show up without looking.

+1. I've noticed the same behavior. This has been consistent since at least OS X 10.8.0, but I am currently experiencing this on OS X 10.9.3.

Same for me on macOS 10.13.4 - except I get WiFi lag every 10-12 seconds when Last.fm app (v2.1.36 downloaded from last.fm site) is running. Quitting it fixes the issue.

P.S. Console shows locationd activity.

This issue still exists in Lastfm app 2.1.39 and macos 10.15.6.
Pretty annoying since the wifi latency suddenly jumps every 10 seconds.
