If playing music through the media library, I have found an odd issue.
Any ALBUMS that you enter with an apostrophe (') in the title show "no tracks". All others are fine.
I'm assuming this is something to do with apostrophe use in the program code
So if the command was some thing like [ play album 'rock n' roll' ], it would effectively try to find an album called 'rock n'. Just a guess though.
Just to clafify, these albums play fine via the regular folder browser.
