Bug 1089718 - [music] Make the metadata parser sane

I suppose that phones with larger screens will typically have more memory and will be better able to decode the full-size album art without fearing OOMs. So maybe you can always have smallish thumbnails and on devices that need bigger ones you can just decode full size.  Maybe add a comment here, at least indicating that you're aware of the issue. Or even file a followup bug and reference it here.
