How Do I Delete Low Bit Rate Songs From My Library

Make bit rate one of the columns displayed in library view. Once you do that, filter everything out until you end up with just the bit rates you want to delete. Once you have them isolated, highlight and delete them. I don't know if Jriver supports this type of thing so you may have to use a different music player. I'm pretty sure can do this with Quod Libet, Clementine and probably foobar.

Yes, both are correct. Click on files and list by bit rate once narrowed down to the ones you want to delete >> select one then click "Control A" which will select them all. Right click and select delete from media center library and computer. This choice will remove all traces of these files from your My Music library and JRiver MC library.

Tom.....I want to kiss you square on the mouth. The Control A thing saved me clicking on 4500 individual songs. Look in the mirror and see the guy that saved me. Thank you!!!!!

Tom....I just did it.....and you're suggestion solved all my problems with the duplicates. I can't thank you enough Tom..... :)

I'm really glad he liked Tom's answer the best.
