Incorrect bitrates/durations showing in search results

I often find that when searching for files, the bitrates/durations shown under 'Attributes' in the search results are not the same as the actual bitrate/durations of the files that are downloaded. The same song can be shown as available from two different people with an identical filesize, but different bitrate/duration. Eg. File 01 shared by User1 - 9,900,633 / 320 CBR, 4m7s - correct information. File 01 shared by User2 - 9,900,633 / 128 CBR, 10m18s - same file, incorrect information, but fine when downloaded. It's not really possible to make use of all of the great new filters in searches because of this. Thanks!
