Ok since this has something to do with music and I'm always finding new ish, just in case u are;nt hip here are two sites that will help you out in your pursuit of music knowledge AND free downloads.... :>)
1. Who Sampled: http://www.whosampled.com/
Basically if you're a music listener who always has the question, "WHERE have I heard this before?" then this site is for you. Who Sampled not only gives you the information as to what song sampled what, it also gives you a sound clip to hear the influence as well as the song that includes the sample! I found this in the midst of my search to find out what song Mc Lyte sampled for "Poor Georgie" ("Georgie Porgie" Toto, AND "Wanna Be Where You Are" Michael Jackson)
2. Fetch MP3: http://www.fetchmp3.com/
I found this googling how to rip audio from YouTube videos about 6mths ago. With this site, you can rip the audio into an MP3 file from ANYthing that has been posted on youtube. So that audio from House Party 2 that you want to include in your podcast? It's on Fetch MP3. That song that came out yesterday that all the links are broken to? You can probably find it on Fetch MP3. I've downloaded COUNTLESS songs from this site and the major PERK, you don't have to download MORE software to your PC it's all done through the browser :>)
NOW that I let go of some of my secrets, take them and use them WISELY! Audi 5000! *muah*
