In my box of music I found an album that might be helpful to you if want to do commercial researching on the go. Tee-Vee Toons released an album called The Commercials which is a wonderful album filled with commercial jingles and commercials and to add to the fun lyrics for each commercial jingle featured in the album so you can do fun karaoke to your favorite commercials while you research. This album is out of print right now but if you can find it get it if you can because it's a fun commercials album. When I listened to The Commercials album it reminded me of radio commercials and it's my favorite commercials album
