Windows – ID3 tagging by “/artistname/albumname” directory structure

Not perfect, but with the plugin foo_run for foobar2000 you could easily launch a web search with your tags (fb2k is to iTunes what firefox 3.5 is to IE 6...)

So, now that everything is installed, to launch a bm4djs.com search on artist & title with foo_run, add a new service with this path properties (in foobar2000 preferences > tools > run services):

http://www.bpm4djs.com/index.php?app_mode=search&search=true&site=1&sv_artist=$replace(%artist%, ,+)&sv_title=$replace(%title%, ,+)&sv_accuracy=tolerant&sv_genere=4&submit=Go

for album & title:

http://www.bpm4djs.com/index.php?app_mode=search&search=true&site=1&sv_title=$replace(%title%, ,+)&sv_album=$replace(%album%, ,+)&sv_accuracy=tolerant&sv_genere=4&submit=Go

for artist alone:

http://www.bpm4djs.com/index.php?app_mode=search&search=true&site=1&sv_artist=$replace(%artist%, ,+)&sv_accuracy=tolerant&sv_genere=4&submit=Go

for artist & bpm (if your bpm tag name is "BPM"):

http://www.bpm4djs.com/index.php?app_mode=search&search=true&site=1&sv_artist=$replace(%artist%, ,+)sv_bpm=%bpm%&sv_accuracy=tolerant&sv_genere=4&submit=Go

etc...

You could certainly tweak it better with the foobar2000's title formatting and a little study of the search url of bpm4dj or any other website...

And, cherry on the cake, foobar2000 recently got a BPM plugin, it's still in early stage but the dev looks motivated.
