Multiple genres in file tags are discarded upon import

[swt30]

I have a bunch of mp3 files tagged with multiple genres. When I import these, all the genres after the first get dropped. This isn't using the lastgenre plugin or anything, just copying across the existing metadata. It's happening because the importer takes just the first value from the list which is created from the genre fields.

I'm new to this open source thing so I dove in and fiddled around to try and work around this. I ended up storing any list style field as a a newline-separated join of the list values (4ce0c95) and splitting it up again when writing the file. It's clunky but it works for what I need, and allows me to search for multiple genres using beet ls genre:one genre:two. I don't know if this is the behaviour you want here, but I thought I should point this out, since I guess it could cause metadata to be lost upon import from any field which uses a ListStorageStyle.

Thanks for mentioning this! We're working on a solution in #119 and, more generally, #505. Any help we can get therein would be hugely appreciated. 😃
