In Library > List Options we can select a number of list types to to be available. This is great! However, when we view a list, select an item within a list, the way the next list is itemized is limited (sub-list). Yes, the items within a sub-list can be sorted in certain ways, but the items in a sub-list are not customizable (sp). For example: If I select to View a list of Genres and then select the Genre list item "Jazz", I get a sub-list of "Genre Albums", but I would much rather see a sub-list of "Artists". It is difficult enough to maintain mp3 tags with the proper titles, artists and genres. The nice thing about having music packaged into single songs per file is that we don't need to have "albums" -- ie. we can pick and choose songs from many albums by the same artist we like, and choose to not collect the rest of the songs from those albums. Therefore many of us have many incomplete albums from the same artist, and we LIKE it that way! I would rather select a Genre from a list and then be presented with a list of all the Artists within that Genre, rather than a list of all the incomplete albums within that genre, especially when I have one one song from one album, three from another, four from a collection album, and 5 songs with no album tags, all from the same artist. So I am thinking that since we already have the ability to customize what lists types will be selectable, and then customize the way the sub-list is sorted, maybe we could also have an option to what kind of sub-list will be displayed. maybe we could customize our own tree of lists > sub-lists > sub-sub-lists (:-), ie: Genre > Artists > Songs Artists > Albums > Songs Genre > Composers > Artists > Songs <-- very useful for classical music Genre > Composers > Songs > Artists Genre > Songs > Artists <--- useful for jazz standards recorded by so many artists over the years All of these ways of listing music are useful, and I imagine users would come up with more to suit their particular listening preference for any given session. I am glad I bought Poweramp, and thanks for taking the time to consider this suggestion.
