Just as an FYI - this is a very bad setup.  You should have 1 (or maybe 2)
VGs set up for these filesystems.  For a normal system, having a single
VG is far more flexible.  You can then "share" all of the unused PEs and
add them to whatever LV needs them.  If you have separate VGs, then you
are not much better off than having DOS partitions.

I would also suggest that you create these LVs as small as possible.  On
Debian in particular, you can have /usr almost 100% full, and only extend
it as necessary to install new packages.  Same with /home and /home/music -
give yourself a "reasonable" amount of free space in each, and leave the
rest unallocated, so you can add it where it is needed later.
