BS”D
Kapusta, Simon and Garfunkel wrote some of the music for AKA Pella and Beatachon (the former of which is VERY problematic for the three weeks and is best listened to during the year.) :).
I used to listen to the Jewishbroadcast.com 3 weeks broadcast but I found it made me miss real music too much and one night I ended up forgetting it was the three weeks and turned on the real thing. So, I stay away. Otherwise, I would probably be OK with plain vocal albums; cannot remember which they are as I left them in the US when I moved out here.
Ames, that is a question for a rav, but from your description, why do you WANT to practice LOL?
