Summary0016515: CPU Utilization always at 25% when Autolookup is enabled
DescriptionIn builds 1902/1903, CPU utilization is always at 25%.

I'm not sure which build this was introduced in, but (release) doesn't exhibit this issue.
Steps To ReproduceThis is from user PC steps to get 20% CPU Usage and to replicate Rusty behavior:
0. Make sure that Auto lookup AA and Lyrics + Auto save tags disabled
1. Start MM (IDLE is around 0-1%)
2. Enable Auto lookup AA and Lyrics + Auto save tags (IDLE should be still low 2-5%)
2. Restart MM
3. MM CPU usage in IDLE 17-20%
4. Disable Auto Lookup
5. Restart MM
6. MM IDLE Usage back to 0-1%

Note: on further testing, it's related to the fact that I have a tab open containing a playlist. i.e. the bug only occurs upon clicking a playlist node (not an AutoPl0aylist node).

On further testing, the bug _does_ occur in build 1897 as well upon selecting the Now Playing node or a Playlist!

On further testing, the issue seems to occur when specific tracks are included in either a Playlist or the Now Playing list.
The following playlists each contain a single track which triggers the issue:
Test 2032 : Depeche Mode - Sacred
Test2033 : Depeche Mode - Little 15

Note that this appears to be a database issue rather than a track-specific issue since scanning these tracks into a new database and adding them to a playlist fails to trigger the bug.

Full DB shared offline.

I can replicate the issue on Rusty's config and is related to artwork lookup (as it does not happen when '[ ] Search for missing artwork' is disabled).

Sounds like the same issue that we have been solving here:
