I love simple apps that solve common problems quickly and easily. Some of the apps I consider to be the best are not elaborate by any means, they're just outright simple and get the job done. One such app that I've grown fond of is called Cover Grabber. It's sole purpose of existence is to simply allow you to search for an album and artist name, get the cover art for said album, and download it.
Once downloaded, the cover art can be added to any album folder on your device or SD Card and you'll no longer have to deal with the generic album cover art in your music player. In some cases you may need to rename the image file to folder.jpg but that's nothing to really worry about. A small, free app that makes my life easier and is available for all BlackBerry 10 smartphones. Got to love it.
