I had to say this

A remix is an alternative version of a song, different from the original version. A remixer uses audio mixing to compose an alternate master recording of a song, adding or subtracting elements, or simply changing the equalization, dynamics, pitch, tempo, playing time, or almost any other aspect of the various musical components. Some remixes involve substantial changes to the arrangement of a recorded work, but many are subtle, such as creating a "vocal up" version of an album cut that emphasizes the lead singer's voice. A song may be remixed to give a song that was not popular a second chance at radio and club play, or to alter a song to suit a specific music genre or radio format. Remixes should not be confused with edits, which usually involve shortening a final stereo master for marketing purposes.

My first remix was with t.A.T.u. and Linkin Park-Gomenasai/My december and after that i tried a hardrock mix with t.A.T.u. and Korn-Ice ice baby=>well i want to be honest with you this 2 songs wer an epic fail :P
At that time i was using some outdated software like Acoustica MP3 Mixer,and i had no idea what was a downbeat ,how to match the tempo,or how to find the right key-i was just playing it by ear,and playing it by ear is a hit and miss job cause most of the time 2 songs don't have the same tempo so they won't match...don't get me wrong Acoustica MP3 Mixer is a great program and i still use it to make a demo of the original song,but it's very limited in what it can do-for example it doesn't even come close to Logic Pro or ProTools LE.
That's why my first songs weren't that good because i couldn't make them continuous and i also didn't use an acapella or an instrumental-truth. :)
in my next blog entries i will start posting my mixes and remixs for you guys to listen and enjoy. :)
