When a server advertises Search with a upnp:class predicate, Serento takes a fast path instead of walking the tree album by album.

I haven't been able to test this with Serento because I'm on Android, but you may have issues when building albums from tracks because of the way tracks can be grouped (represented as albums within albums, typically for classical works).

Using the album Foxtrot by Genesis as an example, the final 7 tracks form part of the broader work Supper's Ready, so all are tagged with GROUP='Supper's Ready', which when displayed on a control point looks like:
   
Your search would return (only a partial listing included):

As you can see tracks 6 and 7 appear to belong to a different album. Maybe you could use the parentID (not = "0$:items") to trigger an album by album approach?

During a previous discussion @simoncn mentioned that it's possible for a control point to request that multi-valued items be delivered individually (artist, genre e.t.c.) so it might be worth chasing up with him on that. What I don't know is if that would apply to users using the .displayFormat setting to display collaborations e.g.
   

Here's a truncated version of the Foxtrot album for testing.
