Hey,
Migrating to gmusicbrowser from Foobar. All seems pretty good so far, and this looks like the most capable player on Linux I've yet come across. However one this missing -- it looks like it can't deal with multiple Title tags (or really, multple anything tags except for artist). This gets used a lot in folk music where a track may consist of multiple short tunes to make up one "set". Is there any way to get gmb to recognize these tags?
Cheers
