Question: Are these songs on a standard micro sd that will work in any mp3 or something they have made to fit special units?
Document: We thought we were buying an sd card to play music from any device that takes an sd card. It is a mini but doesn't work when put into an adapter. Only way to play it is to buy a slot radio player which apparently they don't make anymore. We couldn't return it because it had been opened. BUMMER! !
This is a great value for 1000 songs. And it really is a plug and play pre-loaded card. Simply do requisite battle with packaging, plug the micro sd in (Sansa Clip+ in my case), allow the player a couple minutes to 'refresh media' and it's all there.So far, as I am new to both the Clip+ and the card, I am listening in random shuffle mode, skipping forward when I don't like a song. In this mode, I would prefer the card were not pre-sorted by 7 categories and did a shuffle of all content.
Way too expensive for the old songs it contains. It's designed to fit my sandisk but it costs as much as the sandisk itself.
this product is wonderful,, the songs are great and sound very clear,, great for walking or any kind of exercise.. brings back good memories , keep in beat with the sounds as you work out ..
I really love the slotRadio cards. I have two[rock and Motown] for my Sandisk and use them constantly at work. I don't like the hassle of finding music online and downloading and the price is well worth for how many songs are on it.
Does not work like advertised as there is no music so must return it! I must return it ASAP for another.
I needed a way to listen to my favorite artists and you provided that. I do enjoy my music as I work in the yard or if I want to relax in the sunshine. Thanks again
The slot Card must have every rock music song since 1980. There are some classics still playing on air and some very obscure works from even more obscure artists. It's a refreshing experience to not know the next song in order and have to press buttons to identify the artist. The only down side, which is why 4 stars, is the heavy metal section. It is really bad. There are about 3 featured groups, none that easily stand out, and every song they made must be on this disc. They all sound the same; different words but same tempo, base thump, vocal style.
It's OK but it should not contain what I think are class B songs. Class B songs are the songs that never were on the top 10.
Only down side is you have to listen to the songs in the order they were downloaded. Can not go back and listen to a song you may have liked. Other wise works great for my need.
Answer: This card is very small and I'm not familiar with the mp3 but I would assume that it would work. However the card stopped working after a month and e-mails to the manufacturer regarding the problem went unanswered. You might not want to purchase one, given the cost, if the card only lasts a month it's not worth it.
