I'm sorry, I forgot about this thread.
If you like to choose about average BMP numbers, something like this
might do it:
Code:
--------------------
-- PlaylistName:BPM
-- PlaylistGroups:
-- PlaylistParameter1:custom:Select BPM:select
20*floor(customscan_track_attributes.value/20)+10,20*floor(customscan_track_attributes.value/20)+10
from customscan_track_attributes where
customscan_track_attributes.module='customtag' and
customscan_track_attributes.attr='BPM' group by
20*floor(customscan_track_attributes.value/20)+10 order by
customscan_track_attributes.value
select tracks.url from tracks
join track_statistics on
tracks.url=track_statistics.url
join customscan_track_attributes on
tracks.id=customscan_track_attributes.track and
customscan_track_attributes.module='customtag' and
customscan_track_attributes.attr='BPM' and
customscan_track_attributes.value>='PlaylistParameter1'-10 and
customscan_track_attributes.value<'PlaylistParameter1'+10
left join dynamicplaylist_history on
tracks.id=dynamicplaylist_history.id
where
audio=1
and dynamicplaylist_history.id is null
group by tracks.id
order by rand()
limit 25;
--------------------
Or if you like to select a free range, you should be able to do
something like this:
Code:
--------------------
-- PlaylistName:BPM Range
-- PlaylistGroups:
-- PlaylistParameter1:custom:Select Low BPM:select
10*floor(customscan_track_attributes.value/10),10*floor(customscan_track_attributes.value/10)
from customscan_track_attributes where
customscan_track_attributes.module='customtag' and
customscan_track_attributes.attr='BPM' group by
10*floor(customscan_track_attributes.value/10) order by
customscan_track_attributes.value
-- PlaylistParameter2:custom:Select High BPM:select
10*ceil(customscan_track_attributes.value/10),10*ceil(customscan_track_attributes.value/10)
from customscan_track_attributes where
customscan_track_attributes.module='customtag' and
customscan_track_attributes.attr='BPM' and
customscan_track_attributes.value>='PlaylistParameter1' group by
10*ceil(customscan_track_attributes.value/10) order by
customscan_track_attributes.value
select tracks.url from tracks
join track_statistics on
tracks.url=track_statistics.url
join customscan_track_attributes as lowbpm on
tracks.id=lowbpm.track and lowbpm.module='customtag' and
lowbpm.attr='BPM' and lowbpm.value>='PlaylistParameter1'
join customscan_track_attributes as highbpm on
tracks.id=highbpm.track and highbpm.module='customtag' and
highbpm.attr='BPM' and highbpm.value<='PlaylistParameter2'
left join dynamicplaylist_history on
tracks.id=dynamicplaylist_history.id
where
audio=1
and dynamicplaylist_history.id is null
group by tracks.id
order by rand()
limit 25;
--------------------
I don't have BPM tags in my own library at the moment, so I've no way
to verify if this works or not.
There is also a "bpm" column in the standard "tracks" table, if this is
filled when you have bpm tags it should be possible to do all this
completely without Custom Scan. In this case the playlist SQL will also
be a bit simpler.
