I don't know if it's already reported... but the filtering elements has a wrong link value when clicking on them.
1. Search for a song
2. Filter by Instrument e.g. Piano
3. Now on the 'Number of instruments' section click on the number of songs that are found for the number of instrument... it should take the value of the 'number of instrument' but it takes the number of the found results instead.
