Why when I download from here the tracks lose their quality right after download??? Some really good and helpful stuff on here but the quality ends up being so bad. Please help!

are you talking about whitelabel tracks? they will only sound good while using ssl or itch....there's an intentional quality loss if you try and take them elsewhere like itunes...

Hi Kristen Knowles,

WL.MP3 files have 2 audio streams:
- High quality when you're DJing.
- Low quality when you're organizing (or playing in iTunes).
