[feature request] Advanced search

[hakko]

One feature I've had in mind for a while and hope to work on during Christmas break is a more advanced search function for tracks. For example, "give me all tracks added to my library over the last three months where the artist is tagged as 'folk'".

If you have good ideas for such a feature, or like the implementation in other music players, feel free to post a description or a screenshot that I'll understand as creative input!
