Wiki and even lyric search rarely but sometimes return incorrect result but have no way around it.
When listening to my Train Album i was greated with WIKI on the choo choo train

Wiki lists train (band) but i could click new search and change the ketywords



In Cover Manager fetch cover from amazon once a
cover is found it displays it.
But if it is incorrect you may click new search and change the search keywords. (some albums are named different to america).
