Can I tag mp3 file such a way that banshee or rhythmbox music player can recognize the multiple artist separately. Right now the different artist are showing together like Arijit Singh & Harshjeep. I mean banshee is recognizing the whole entry as a separate artist, not individual one. So I can't effectively filter music using artist's name.
I can't answer re: Rhythmbox, but this is a known bug in Banshee, and has been for some time. There is no satisfactory workaround. Banshee's behaviour is as follows:
If there are multiple Artist tags on a file (achievable with, exempli gratia, an external tag-editor) it will concatenate them, using a delimiter to treat them as a single tag. As I recall, this delimiter is a semicolon, although I could be wrong (I don't actually have a local music library with which to check...). Banshee will then treat the resultant text ("artista; artistb") as the artist tag.
When Banshee encounters an artist tag, including one it's just constructed, that contains a delimiter, it does no special processing on it at all and treats it as the single-artist artist tag.
Yes, it's a pain. No, I don't know what can be done about it. Sorry.
I don't know about you, but the thought of editing tags for several thousand tracks one by one is beyond what I'm willing to do.
easytaghas bulk editing which allows you to change one field of one or ten or a thousand tracks at once without disturbing any other tags.
