Help me switch a friend to Ubuntu please

[Hubertus Hiden]

Hello,

in the past I've managed to convert a lot of my friends from Windows to 
Ubuntu users.
But in one case I got stuck somehow. The problem is Rhythmbox. My friend 
has 2 USB Harddisks both filled with a few 10.000 songs. Both HDs have 
been imported into the player. But everytime a disk gets 
diconnected/connected the songs are moved in/out of "unavailable songs". 
This procedure takes about 20 minutes.
Does anybody know of a music player that handles this situation better ?
Or can Rythmbox be tweaked in some way ?

Many thanks for any response,
Hubertus
