I've noticed many a time that on some radio channels (FM), the pitch of a song is slightly higher than that of the normal version. I don't know if this is done on
purpose, or something caused by the different radio frequencies as the same song can sound fine on other channels. With all this in mind, I do like the higher
pitched songs, sometimes more so than it being played normally. It somewhat makes the song sound "happy"(not in the literal sense), and allows you to hear the
lower beat more effectively. I don't know. Has anyone else ever experienced this?

Some TV stations were caught speeding up old episodes of shows to make more room for commercial breaks, I wonder if the radio stations are doing the same thing.

You may be on to something, sometimes it can only happen to one song and not the next, although it feels like the pitch is changing and not the longevity.

How did you notice this? Do you have perfect pitch?

Maybe, but I'm not THAT good with music to notice everything perfectly. If you have a video or audio editor/player, play a song normally and then increase the pitch by .5 semitones. That is what this sounds like.

it would be odd if it was just the pitch and not the length as well
it would be really easy to explain it as the station just running the tune slightly faster, whether out of preference or due to some mismatch with the playback system vs the original recordings (file is recorded at 44.1kHz sample rate, and played back at 48kHz, for example) but I am 100% guessing

I can't really tell though - I have okay pitch accuracy but not enough to tell a quarter step up/down like >>5 describes
